Here’s what has happened in the meatpacking industry in the last week alone:

A federal food safety inspector in New York City, who oversaw meat processing plants, died from the illness caused by the novel coronavirus.

A poultry worker in Mississippi, employed by America’s third largest chicken company, tested positive for the virus, causing a half-dozen workers to self-quarantine. Another worker in South Dakota, employed by the world’s largest pork producer, also tested positive.


In Georgia, dozens of workers walked out of a Perdue Farms chicken plant, demanding that the company do more to protect them.

And Tyson Foods told ProPublica on Friday that “a limited number of team members” had tested positive for the disease.

As COVID-19 makes its way across the country, leading to panic grocery buying in state after state, the stresses on the nation’s food supply chain have ratcheted ever higher. But in industries like meatpacking, which rely on often grueling shoulder-to-shoulder work, so have the risks to workers’ health.

In interviews this week, meat and poultry workers, some in the country without authorization, noted with irony that they have recently been labeled “essential” by an administration now facing down a pandemic. Yet the rules of their workplaces — and the need to keep food moving — pressure them to work in close quarters, even when sick.

And it’s unclear how federal regulations that traditionally protect workers from harm in their workplaces will address a potentially deadly coronavirus.

“They are listening about social distancing on the TV and some of them try to practice it in their home, but when they go to work, they can’t do it,” said Father Roberto Mena, who ministers to many poultry workers at St. Michael Catholic Church in Forest, Mississippi.

Many of the nation’s meatpackers declined to respond to specific questions about how they’ve dealt with infected workers or what they’ve done to try to mitigate the spread of COVID-19 in their plants. Or they offered vague assurances that workers are being protected.

So far, only two meatpacking companies — Tyson Foods and Cargill — have announced companywide temperature checks to screen employees for signs of the virus. Two more say they have begun rolling them out.

But except for unionized plants, meat and poultry workers rarely get paid when they’re sick. At many companies, including Tyson, workers receive disciplinary points for calling in sick. Because points lead to termination, workers told ProPublica, they and some of their colleagues have continued to work even when sick, despite the coronavirus.

“We are all afraid,” said Maria, who works on the evisceration line at a Tyson plant in Arkansas and asked to be identified by her first name. “The problem is if people feel sick, they’re not going to say anything because they need the money. They don’t want the points.”

In an email, Tyson said it had recently altered its policies to allow workers who contract the coronavirus or exhibit symptoms to apply for short-term disability without a waiting period. “This is an evolving situation and we’re continuing to consider additional measures to support our team,” spokesman Worth Sparkman said. “We don’t want team members who feel sick to come to work.”

Tyson announced this month it was “eliminating any punitive effect for missing work due to illness.” But Maria said that at her plant, nothing had changed.

Despite the “essential” role meat and poultry workers play in the food chain, the sick-time bill signed by President Donald Trump last week doesn’t cover most meat and poultry workers because it exempts companies with more than 500 employees.

The uncertain economy, with millions of people filing jobless claims last week, is adding to the tension.

At Koch Foods in Mississippi, Ramirez, an undocumented Guatemalan immigrant who asked to go by his last name, said a woman who worked near him showed up for her shift last week with a heavy cough. But after she told her supervisor, he said, she was told she couldn’t come back. The message was clear, he said. So, when he started feeling sick a few days later, he simply kept quiet and continued working.

“People are worried,” Ramirez said, that if they say they are sick, “they’ll fire us.”

Going to the doctor is not an option, he said, because he doesn’t have health insurance and fears it could expose his immigration status.

Koch Foods didn’t respond to calls and emails asking about its policies for sick workers.

Even before the coronavirus, the meat industry had complained of a labor shortage as low pay and harsh conditions collided with a tight labor market, tighter borders and dramatic reductions by the Trump administration in the number of refugees, who make up the backbone of many plants’ workforce.

While there’s no evidence that the coronavirus can be transmitted through food, workers say they fear it could spread among them, even though they wear butcher coats and latex gloves, and the plants are sanitized every night.

If it does, it could take out a critical cog in the nation’s food supply chain just as it struggles to keep up with increased demand, workers and their advocates said. Grocery meat sales, excluding deli meat, surged a staggering 77% for the week ending March 15, according to one industry analysis.

To meet the demand, companies have been scrambling, adding additional weekend shifts and changing lines to produce whole birds and bigger cuts of beef. Under pressure from unions and wage increases at supermarkets and warehouses, some companies like Cargill and National Beef have announced temporary $2 per hour bonuses for the next several weeks to retain their workers and reward them for sticking through difficult times.

Company executives have said that the empty shelves aren’t a sign of a food shortage and that they’re capable of meeting the surge, aided in part by lower demand from restaurants that have been ordered to close.

“Our primary focus is to keep our plants running so that we can feed America,” Tyson’s president, Dean Banks, said on CNN. “We’re running the plants as hard as we can.”

And some analysts note that even if an outbreak of the virus forced a plant to close, the industry — with more than 500,000 employees at 4,000 slaughterhouses and processing plants across the country — is big enough to absorb the loss.

Tim Ramey, a retired food industry analyst, said “there could be significant disruptions” in a company’s output if an outbreak occurred. But supermarkets and restaurants buy meat from many suppliers, he said, and another plant could pick up the slack.

“There are plenty of ways you could have risk to the worker supply,” Ramey said. “I doubt that would be enough to disrupt the food supply.”

But no one knows what would happen if multiple plants suffered outbreaks.

The closest precedent may be immigration raids, which have temporarily shuttered meat and poultry plants periodically over the last 25 years. For months after, those plants struggled to find new workers and ramp up to speed. But the supply lines continued to feed America.

Some immigrant workers caught up in those raids now marvel that the country is leaning on them. Last summer, after finishing his shift pulling the guts out of thousands of chickens, Ramirez flipped on his TV and watched in shock as immigration agents descended on central Mississippi, rounding up hundreds of his coworkers in the Trump administration’s biggest immigration sting.

In the weeks that followed, Ramirez watched the three children of a friend who’d been detained and hunkered down at home, fearing he could be next. It was easy to feel disposable, he said, especially when Trump praised the raids as “a very good deterrent.”

Now, when Ramirez watches the news, Trump is calling workers like him “critical,” telling them, “you have a special responsibility to maintain your normal work schedule.”

“I don’t understand, if they have a big need for all of the workers,” Ramirez asked, “why aren’t they worried about us?”

The slaughtering of chickens, hogs and cattle has become increasingly automated in the last few decades. But several tasks on the disassembly line still have to be done by hand. In poultry plants, in an area known as “live hang,” workers in a small, black-lit room crowd around a trough grabbing live chickens by their feet and hanging them on shackles.

In another area known as “debone,” workers stand side by side cutting raw chicken into breasts and tenders, so close that they occasionally cut coworkers with their knives.

In pork plants, workers are so packed together that a little over a decade ago, two dozen workers at a Minnesota factory developed a neurological illness from inhaling aerosolized pig brains that drifted from a nearby station that was making an ingredient used in stir-fry thickeners.

So even as everyone from the president to Snoop Dogg are urging people to stay home and avoid groups of more than 10 people, meat and poultry workers are required to do the opposite.

ProPublica asked the nation’s largest meat companies what they were doing to try to achieve social distancing. Cargill, which produces billions of pounds of beef and turkey for supermarkets and restaurants each year, was the only company that said it was doing anything other than staggering start and break times. Daniel Sullivan, a spokesman for the Minnesota-based meatpacker, said it had increased spacing in its factory work areas and put up partitions in its cafeteria.

The evisceration line where Maria, the Tyson employee, works doesn’t have as many people as other parts of the factory because it is heavily automated. But she said that because workers can’t leave the line unless it’s an emergency, she regularly encounters large crowds as everyone rushes to the bathroom during breaks. The company has placed hand sanitizers at the entrance, she said, but inside the plant, the bathrooms don’t always have paper towels.

As COVID-19 cases at the plants become public, workers fear it’s only the beginning.

On Monday, Sanderson Farms, the nation’s third largest chicken company, said an employee at its McComb, Mississippi, plant had tested positive for the virus. Sanderson said the employee’s work area was contained to one small processing table. In response, the company notified its workers and sent six other employees in the work area home to self-quarantine with pay.

The company did not respond to calls or emails seeking additional information.

On Thursday, a worker at pork producer Smithfield Foods’ plant in Sioux Falls, South Dakota, tested positive. The company told the Argus Leader that the employee’s work area and all common areas were “thoroughly sanitized.” But it did not say anything about workers who might have come in contact with the employee.

There have been even fewer details about the federal food safety inspector who died. U.S. Agriculture Secretary Sonny Perdue said in a statement that he was “terribly saddened to hear” that one of the department’s employees had passed away due to the coronavirus and thanked “those working on the front lines of our food supply chain.” But the department did not specify which plants the inspector had worked in or what had been done to alert or quarantine others the inspector may have been in contact with.

Paula Schelling, a union representative for the nation’s food inspectors at the American Federation of Government Employees, said the USDA’s Food Safety and Inspection Service needs to do more to protect its front-line workers.

“FSIS is doing nothing to provide any protection for any employee who is out in the field,” she said. “They are just saying, ‘We are following the CDC guidelines.’ What does that mean to us?”

Concerns that meat companies aren’t being forthcoming have already led to increased anxiety at several plants. Workers who walked out of the Perdue plant in Georgia said the unrest started because supervisors dismissed concerns that some employees were continuing to work despite being in contact with people who had the coronavirus.

“We’re not getting nothing,” Kendilyn Granville told a TV news reporter outside the plant Monday night. “No type of compensation, no nothing, not even no cleanliness, no extra pay — no nothing. We’re up here risking our life for chicken.”

Perdue spokeswoman Diana Souder said that after speaking with managers, the majority of those who walked out returned to work.

“We know that many are feeling anxious during these uncertain times and we’re doing everything we can to take good care of our associates while continuing to produce safe and reliable food,” she said.

Typically, when workers feel unsafe, they can complain to the Occupational Safety and Health Administration. But it’s unclear how OSHA will respond to complaints related to the coronavirus. The agency, which has seen its ranks depleted under the Trump administration, has issued guidance for employers. But there is no specific standard related to the virus, and the agency has not said how it might interpret its general duty clause, which requires employers to keep their worksites free from recognized hazards that might cause death or “serious physical harm.”

Employers are only required to notify OSHA when an employee is hospitalized, suffers an amputation or is killed at work. But under a patchwork of rules, some employers might have to notify their state and local health departments.

As cases started to pop up this week, some employers began offering additional pay. Perdue said it would provide all hourly workers a $1-per-hour raise for the next several weeks. Hormel, the maker of Spam, said it would offer a $300 bonus for full-time workers and $150 for part-time associates.

On Thursday, the United Food and Commercial Workers, which represents 250,000 food processing workers, said it had negotiated additional pay and benefits increases, including a $600 bonus in May for its members at the nation’s second-largest meatpacker, JBS, which includes Pilgrim’s chicken. JBS spokesman Cameron Bruett did not answer whether the company would match that for nonunion employees.

Several large meat and poultry companies, including Tyson, Smithfield, Sanderson and Koch, have not announced raises or bonuses.

On Friday, Perdue told ProPublica it was starting to roll out temperature checks at its plants. And Bruett said JBS had set up “triage stations” outside plants to screen employees for temperature and symptoms. But it’s unclear if all employees will be tested or only those exhibiting symptoms.

Meanwhile, Venceremos, a group advocating for poultry workers in northwest Arkansas, has started a petition asking that Tyson and other processors provide paid sick leave for workers as the coronavirus begins to spread to rural America.

“Everyone is realizing that they are essential and have been essential to the country,” said Magaly Licolli, one of the group’s leaders. “And now it’s time that everybody should demand fair rights for them. That’s what we’ve been arguing all this time. They are the ones that provide for the country.”

  • GLP‑1 drugs may fight addiction across every major substance, according to a study of 600,000 people

    GLP‑1 drugs may fight addiction across every major substance, according to a study of 600,000 people

    A massive study of veterans suggests these medications may quiet cravings far beyond food.

    A patient of mine, a veteran who had tried to quit smoking for over a decade, told me that after he started a GLP-1 drug for his diabetes, he lost interest in cigarettes. He didn’t use a patch. He didn’t set a quit date. He simply lost interest. It happened without effort.

    Another patient on one of these drugs for weight loss told me that alcohol had lost its pull – after years of failed attempts to quit.

    People struggling with many addictions, ranging from opioids to gambling, are reporting similar experiences in clinics, on social media and around dinner tables. None of them started these drugs to quit. This pattern of people losing their cravings across a broad range of addictive substances has no precedent in medicine.

    But my patients were giving me an important clue. People taking GLP-1 drugs often talk about “food noise” vanishing: the constant mental chatter about food that dominated their days simply goes quiet. But my patients were reporting that it wasn’t just food: They were noticing that the preoccupation with smoking, drinking and using drugs that drives people back despite their best intentions to stop was going quiet too.

    As a physician whose patients are often on GLP-1 drugs, and as a scientist who works on answering pressing public health questions – from long COVID to medication safety – I saw a problem hiding in plain sight: Many addictions have no approved treatment. The few medications that exist are massively underutilized, and none works across all substances. The idea that a drug already taken by millions might do what no addiction treatment has done before was too important to ignore.

    My team and I set out to test whether GLP-1 drugs – medications like semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro and Zepbound), originally developed for diabetes and then approved for obesity – could do what no existing addiction treatment does: curb craving itself.

    Our evidence strongly suggests they can.

    Biological basis of cravings

    The hormone that these drugs mimic – GLP-1 – is not only produced in the gut. It is also active in the brain, where the receptors it binds to cluster in regions governing reward, motivation and stress – the same circuitry that gets hijacked by addiction. At therapeutic doses, GLP-1 drugs cross the blood-brain barrier and dampen dopamine signaling in the brain’s core reward center, making addictive substances less rewarding.

    GLP-1 drugs seem to inhibit cravings for several different substances in multiple animal models. For instance, rodents given GLP-1 drugs drink less alcoholself-administer less cocaine and show less interest in nicotine. When researchers gave semaglutide to green vervet monkeys – primates that voluntarily drink alcohol much like humans do – the animals drank less without showing signs of nausea or changes in water intake. This suggests the drug lowered the reward value of alcohol rather than making the animals feel sick.

    From animals to people

    To find out whether these drugs have a similar effect on people, we turned to the electronic health records of more than 600,000 patients with Type 2 diabetes at the U.S. Department of Veterans Affairs – one of the largest health care databases in the world.

    We designed a study that applied the rigor of randomized controlled trials – the gold standard in medicine – to real-world data. We compared people who started GLP-1 drugs to people who did not, adjusting for differences in health history, demographics and other factors, and followed both groups for three years.

    My team and I asked two questions: For people already struggling with addiction, did the drugs reduce overdoses, drug-related hospitalizations and deaths? And for people with no prior substance use disorder, did GLP-1 drugs reduce their risk of developing one across all major addictive substances: alcohol, opioids, cocaine, cannabis and nicotine?

    What we found was striking. In the group already struggling with addiction, there were 50% fewer deaths due to substance use among those taking GLP-1 drugs compared with those who were not. We also found 39% fewer overdoses, 26% fewer drug-related hospitalizations and 25% fewer suicide attempts. Over three years, this translated to roughly 12 fewer serious events in total per 1,000 people using GLP-1 drugs – including two fewer deaths.

    Reductions of this magnitude are rare in addiction medicine – and what’s remarkable is that the finding came from drugs initially designed for diabetes, later repurposed for obesity and never intended to treat addiction.

    The drugs also appeared to prevent addiction from developing in the first place. Among people with no prior substance use disorder, those taking GLP-1 drugs had an 18% lower risk of developing alcohol use disorder, a 25% lower risk of opioid use disorder and an approximately 20% lower risk of cocaine and nicotine dependence. Over three years, this translated to roughly six to seven fewer new diagnoses per 1,000 GLP-1 users.

    With tens of millions of people already using GLP-1 drugs, the reductions in deaths, overdoses, hospitalizations and new diagnoses could translate into thousands of prevented serious events each year.

    Converging evidence

    Our findings align with a growing body of evidence.

    A Swedish nationwide study of 227,000 people with alcohol use disorder found that those taking GLP-1 drugs had 36% lower risk of alcohol-related hospitalizations. This is more than double the 14% reduction that the same study found with naltrexone, which was the best-performing medication approved for treatment of alcohol use disorder in that analysis. Other observational studies have linked GLP-1 drugs to lower rates of new and recurring alcohol use disorderreduced diagnoses and relapse in cannabis use disorderfewer health care visits for nicotine dependence and lower risk of opioid overdose.

    Meanwhile, randomized controlled trials that directly test whether these drugs help people with addiction also show promise. In one trial, semaglutide reduced both craving and alcohol consumption in people with alcohol use disorder. In another, dulaglutide reduced drinking. More than a dozen additional trials are already underway or actively enrolling, and several more are planned.

    The future of addiction treatment

    GLP-1 drugs are the first type of medication to show potential benefit across multiple substance types simultaneously. And unlike existing addiction medications, which are prescribed by specialists and remain vastly underused, GLP-1 drugs are already prescribed at enormous scale by primary care doctors. The delivery system to reach millions of patients already exists.

    The consistency of GLP-1 effectiveness across alcohol, opioids, cocaine, nicotine and cannabis suggests these drugs may act on a shared vulnerability underlying addiction – not on any single substance pathway. If confirmed, that would represent a fundamental shift in how society understands addiction and how doctors treat it.

    Some unanswered questions remain, though, about how these drugs would affect addiction. Many people who take GLP-1 drugs to treat obesity or diabetes discontinue them; afterward, their appetite typically returns and they regain the weight they lost. Whether the same rebound would occur with addiction, and what it would mean for someone in recovery to face the roar of craving again, is unknown. Nor is it clear whether the benefits persist over years of continuous use, or whether the brain adapts in ways that dampen those effects.

    Also, because GLP-1 drugs engage the brain’s reward circuitry – the same system that governs not just craving but everyday motivation – prolonged use could, in theory, dampen motivational drive in some people. Whether that might affect real-world outcomes, such as initiative, competitive drive or performance at work, remains an open question.

    What comes next

    GLP-1 drugs have not been approved for addiction, and there is not yet enough evidence to prescribe them solely for that purpose. But for millions of people already weighing whether to start a GLP-1 drug for diabetes, obesity or another approved indication, it is one more factor worth considering.

    A patient living with diabetes who is also trying to quit smoking might reasonably choose a GLP-1 drug over another glucose-lowering medication, not because it is approved for smoking cessation, but because it may help them quit, a benefit that other diabetes drugs do not offer. Similarly, for people living with obesity who also struggle with alcohol, the potential for benefit beyond weight loss could be one more reason to consider a GLP-1 drug.

    If additional trials confirm that they effectively curb cravings across addictive substances, these drugs could begin to close one of the most consequential treatment gaps in medicine. And the most promising lead in addiction in decades will have come not from a deliberate search but from patients reporting a benefit no one anticipated. Like my patient who quit smoking after a lifetime of trying, it happened without effort.

  • Expert shares ancient monk’s mindset for keeping your composure when life ‘bumps’ you

    A snap reaction in a heated moment can be difficult to control. Sometimes an unexpected experience brings out the best in us—or, all too often, the worst. The Mindset Mentor Podcast, hosted by personal coach Rob Dial, explains how cultivating a healthy mindset can help you stay calm and composed when life “bumps” into you.

    Using a story of an ancient monk teaching his students about enlightenment, Dial highlights that whatever we carry within ourselves rises to the surface when life gets hard. Beginning the day with a healthy mindset matters.

    Dial shares a monk’s story about enlightenment

    A monk teaches his students about enlightenment. He asks them to imagine holding a cup of coffee when someone bumps into them, causing it to spill. When he asks why the coffee spilled, the students quickly reply that it was because someone bumped into them.

    The monk responds, “You spilled the coffee because that’s what was in your cup. Had there been water in the cup, you would have spilled water. Had there been tea in the cup, then you would have spilled tea.”

    Dial goes on to explain the impactful meaning behind the monk’s simple philosophy:

    “When life shakes you, which it will, whatever you carry inside of you will spill out. So if you’re carrying anger, or fear, or hatred, or jealousy, then that is what is going to spill out of you in those moments. But, if you’re carrying love and kindness and compassion and empathy, then that is what is going to spill out you.”

    A question to ask before your day

    If this is the challenge we face each day, the real question becomes: how do we prepare ourselves for what life might throw our way? Dial suggests the answer lies in an intentional pause. “Each morning,” he says, “it’s important for you to stop and close your eyes and ask yourself, ‘What am I carrying inside of me today?’”

    That small act of self-awareness can shape everything that follows. If we choose to bring despair, judgment, and negativity, those emotions will most likely surface when things don’t go as planned. But if we choose to center ourselves in kindness and compassion, we’re far more likely to respond with those qualities instead.

    The advantages of morning preparation and a healthy mindset

    Significant time and research have gone into understanding the benefits of a morning routine. These practices help build a kind of “spiritual armor” that prepares us to face the day with confidence. Simple habits like getting sunlight, drinking water, moving our bodies, and practicing mindfulness can boost energy and improve mood.

    A 2024 study found that morning activities like loving-kindness meditation can positively affect people’s mental health. Individuals with a regular practice tend to be more positive, mindful, and compassionate. The length or specific details of the practice have little effect on outcomes when compared with one another.

    Another 2024 study found that framing problems in a positive way helps people recover faster from stress. Staying motivated during difficult situations and feeling more emotionally stable are skills that can be built through mindset. The simple fact is that study after study demonstrates that positive thinking directly supports mental health during difficult periods in life.

    Dial offers a simple concept: what we carry within ourselves influences how we respond to life’s challenges. The students say it’s because they were bumped. The monk explains it’s what’s in the cup. The real preparation for the day isn’t just what we do, it’s what we choose to carry. “What am I carrying today?”

  • The Tsimané people of Bolivia have almost no dementia. Scientists say modern life is our problem.
    A tribe sharing a mealPhoto credit: Canva

    Deep in the Bolivian Amazon, researchers studying two indigenous communities have found something that stopped them in their tracks: among older Tsimané adults, the rate of dementia is roughly 1%. In the United States, the figure for the same age group is 11%.

    The finding, published in the journal Alzheimer’s & Dementia, is part of nearly two decades of research on the Tsimané and their sister population the Mosetén, communities who have been recorded as having some of the lowest rates of heart disease, brain atrophy, and cognitive decline ever measured in science. A subsequent study from the University of Southern California and Chapman University, published in the Proceedings of the National Academy of Sciences, used CT scans on 1,165 Tsimané and Mosetén adults to measure how their brains age compared to populations in the US and Europe. The answer was striking: their brains age significantly more slowly.

    The researchers’ explanation centers on what they call a “sweet spot” — a balance between physical exertion and food availability that most people in industrialized countries have drifted far from. “The lives of our pre-industrial ancestors were punctuated by limited food availability,” said Dr. Andrei Irimia, an assistant professor at USC’s Leonard Davis School of Gerontology and co-author of the study. “Humans historically spent a lot of time exercising out of necessity to find food, and their brain aging profiles reflected this lifestyle.”

    The Tsimané are highly active not because they exercise in any structured sense but because their daily lives demand it. They fish, hunt, farm with hand tools, and forage, averaging around 17,000 steps a day. Their diet is heavy on carbohydrates — plantains, cassava, rice, and corn make up roughly 70% of what they eat, with fats and protein splitting the remaining 30%. It is not a low-carb or protein-heavy regimen. It is, essentially, the diet of people who burn what they consume. CNN’s Dr. Sanjay Gupta, who visited a Tsimané village in 2018 for his series “Chasing Life,” noted that they also sleep around nine hours a night and practice what might be called intermittent fasting — not by choice, but by necessity during lean seasons.

    The research also included the Mosetén, who share the Tsimané’s ancestral history and subsistence lifestyle but have more access to modern technology, medicine, and infrastructure. Their brain health outcomes fell between the Tsimané and industrialized populations, better than Americans and Europeans, but not as strong as the Tsimané. Researchers describe this gradient as especially revealing because it suggests a continuum rather than a binary, and that even partial movement toward a more active, less calorically abundant lifestyle appears to have measurable effects on how the brain ages.

    “During our evolutionary past, more food and less effort spent getting it resulted in improved health,” said Hillard Kaplan, a professor of health economics and anthropology at Chapman University who has studied the Tsimané for nearly 20 years. “With industrialization, those traits lead us to overshoot the mark.”

    The researchers are careful to note that the Tsimané lifestyle is not simply transferable. Their longevity in absolute terms is lower than Americans’ because of deaths from trauma, infection, and complications in childbirth, hazards of living without a healthcare system. The point of the research is not that modern medicine is unnecessary but that the environments it’s embedded in may be undermining the brain health it’s trying to protect.

    “This ideal set of conditions for disease prevention prompts us to consider whether our industrialized lifestyles increase our risk of disease,” Irimia said.
