Health experts are urging residents to stay hydrated and stay out of the sun during peak periods, especially during the heat wave that is gripping parts of Kentucky and the rest of the United States.

According to the Centers for Disease Control and Prevention, older adults, young children, and people with chronic diseases are at highest risk for heat-related illness. But the heat also poses dangers to healthy people, especially during prolonged or strenuous activities in hot weather.

Donna O'Shea, chief medical officer for population health and value-based care at UnitedHealthcare, said people use health-care services a lot more on very hot days, and hospitals report a spike in emergency-room visits.

"And so one thing we do want people to remember," she said, "is that virtual care can help people connect with a health-care professional, 24/7 from their home when they have concerns that arise."

The Department of Health and Human Services has said extreme heat can trigger asthma and chronic obstructive pulmonary disease in some people. Blazing heat can also pose risks for people struggling with mental-health issues, and can worsen acute psychiatric and substance-use symptoms.

Dr. Rob Tagher, president of the American Academy of Pediatrics' Kentucky chapter, said noticeable symptoms of dehydration or heat stroke can include irritability, lethargy or fussiness in toddlers. He explained that it's important to ensure small children stay hydrated.

"I always tell adults that are taking care of kids and toddlers that if you're uncomfortable, the child is much more uncomfortable than you with regards to temperature," he said.

Tagher added that pediatricians often see an influx of young patients with insect bites, poison ivy and other summer rashes. Because there aren't many treatment options available other than waiting for the rash to resolve and trying to alleviate itching, he said prevention is key.

"Knowing which plants to stay away from," he said, "good observation and parenting to keep kids away from more dangerous plants, keeping them away from dawn and dusk, when the mosquitoes and bugs are a lot worse."

It's a well-known fact that factory farms rely on antibiotics to treat animals raised in cramped, unsanitary conditions. Lesser known is the rising quantity of antibiotics needed to do just that. Sales of medically important antibiotics for use in U.S. livestock farming rose over four percent in 2022, compared to a year earlier, and show an overall upward trend since 2018, risking greater human mortality from antibiotic-resistant infections.

Medically important antimicrobials - a broader term for drugs, including antibiotics, that kill microorganisms - are those considered essential for treating human disease. Globally, the livestock industry fed an estimated 99,502 metric tons of antimicrobials in 2020 to the billions of cattle, sheep, chicken and pigs raised for food that year.

Such widespread antimicrobial use has been linked to the development of resistant bacteria and other organisms like fungi. Infection from antimicrobial-resistant organisms is described as a "growing crisis" by the American Public Health Association and other health professionals and scientists.

People and animals infected by resistant organisms are harder to cure. In the U.S., the Centers for Disease Control estimates there are over 2.8 million antibiotic-resistant infections every year. Of those, over 35,000 people eventually die. Globally, one study found there were an estimated 4.95 million deaths associated with bacterial antimicrobial resistance.

Factory Farms Depend on Antibiotics to Raise Billions of Animals

The Food and Drug Administration data show sales of medically important antimicrobials approved for use in farm animals rose 4.3 percent to 6.25 million kilograms in 2022. The 2022 figure is a significant decrease on the 8.36 million kilograms sold in 2016, the earliest year shown in the data. But the 2022 figure is higher than all other years since 2016, indicating a more recent trend in the wrong direction.

Thomas van Boeckel, an expert in global antimicrobial usage and resistance in farm animals, fish and humans, says the upward swing indicates that "unlike some European and Asian countries ... the U.S. is clearly not on a trend that shows its commitment to sustainably reduce antimicrobial use in animals."

The data, he adds, shows the problem is "mostly a pig and cattle issue" and reveals "a dependence" by the livestock sector on antibiotics that has "potential consequences on the continued development of resistance."

Prior to 2016, the use of medically important drugs for livestock was even higher, says Steven Roach of the Food Animal Concerns Trust. To control the problem, federal rules were tightened in 2017 to prevent farmers using the drugs for growth promotion.

By species, the administration's data shows 2022 sales of medically important antibiotics for cattle were up 4.3 percent to 2.57 million kilograms, higher than any other year since 2016. For pigs, sales rose almost 5 percent to 2.66 million kilograms, again higher than any year since 2016.

Treating Healthy Animals Has Deadly Consequences for Humans

Farmers use antimicrobials in three ways, Roach says. "Treating a sick animal, which everyone supports. Treating a particular group of animals, for example if there is a risk of infection from one sick animal, which we also support," he says.

The third use, which Roach opposes and is prohibited in Europe, is treating healthy animals to prevent disease, a practice known as prophylaxis. For example, Roach says, months of preventative treatment of cattle can happen in feedlots where the animal's weight promoting, high energy diet produces a bacteria that can infect their livers. To prevent liver problems, medically important antimicrobials called macrolides are used, Roach says.

Most antimicrobials are fed to livestock via their feed and water. Research has linked the addition of antimicrobials to water with the faster breeding and spread of resistant bacteria between animals and feedlot workers.

The FDA data, Roach added, does not "tell us the percentages of how much of each antimicrobial is used for which category," making it hard to know the level of preventative use.

Not only does Roach agree that the U.S. livestock sector is falling behind other countries in using more, not less, medically important antimicrobials, he says the government appears uninterested in the problem.

"We can't even get anyone in the U.S. government to say that there is a need to reduce medically important antimicrobials in food animals," he says, blaming livestock industry lobbying for the current predicament.

Roach hopes the FDA "will realize it has to act and follow the EU and prohibit the use of [the drugs] for disease prevention." He adds, "the FDA could also set a public health goal to reduce their use, say by 50 percent by a certain year, which is what other countries have done."

Absent government action to prevent prophylactic use of the drugs, Roach says the most successful route to reducing their use in livestock is consumer pressure. "We have had good luck getting big meat buyers to put pressure on companies. The good news is in chicken, it is going down and part of that was pressure on the companies [to reduce their use of medically important antimicrobials] and a choice by Tyson and Perdue to quit using them."

Some companies are avoiding antibiotics altogether. "[Our] family farmers and ranchers prove every day that routine antibiotic use is not necessary when animals are provided a low-stress environment with extra space, fresh air and humane animal care," says Chris Oliviero, who leads the Niman Ranch network of independent meat producers. Niman Ranch animals that must be treated with antibiotics are not sold as meat.

FDA and American Veterinary Medical Health Association Push Back

Neither the National Cattlemen's Beef Association nor the National Pork Producers Council replied to Sentient Media's requests for comment.

Answering the criticisms raised here, the Food and Drug Administration said in an email that it is "committed to the judicious use of antimicrobials in food-producing animals" and that it continues to take "many actions to promote judicious use, reduce inappropriate use .... [and] try to curb the development of antimicrobial resistance (AMR) that could stem from antimicrobial use in food-producing animals."

Those actions, it said, include rules that now ensure "all medically important antimicrobials for food-producing animals are only available under the supervision of a licensed veterinarian."

Asked about policies to restrict antibiotic use on factory farms elsewhere in the world, the email said U.S. laws and livestock population "are not the same as that of the EU or other countries. The FDA's initiatives to promote judicious use and reduce AMR were devised specifically for the U.S."

It added that there are "many factors to consider" when analyzing antimicrobial sales data. These include sales volume fluctuations "in response to various factors, including changing animal health needs or changes in animal populations that may make certain antimicrobial drugs more medically important at various times."

The American Veterinary Medical Health Association also replied, arguing that antimicrobial sales data is "a valuable indicator of market trends" but that it "does not necessarily reflect the actual use of antimicrobial drugs." Pointing to more detailed biomass data, which includes animal weights, the association further suggested that higher animal numbers might be a factor saying that "... overall, animal populations have been growing annually since 2016 ... [which would] impact the amount of antimicrobials sold and could be one factor contributing to an increase in antimicrobial sales."

Yet according to FACT's Steven Roach, a closer look at the data suggests sales may be even higher. "If you look at the more detailed biomass data referred to by the AVMA it shows that animal numbers were down in 2022 compared to 2021 so when corrected for biomass the [medically important anti-microbial] sales increases are even larger."

A newly installed rooftop solar power system will help the Free Clinic of Simi Valley keep its doors open and the lights on for the area's disadvantaged patients.

The Ventura County facility annually serves more than 10,000 uninsured or underinsured, low-income residents. Funding for the project was provided through a grant from the global nonprofit humanitarian aid organization Direct Relief.

Fred Bauermeister, executive director of the clinic, said being mostly "off the power grid" allows them to fund other priorities.

"Despite the fact that we got this building donated, we still have to pay $3,000 a month in electricity, which from a nonprofit point of view, is hard money to raise," Bauermeister, explained. "It's not very compelling when I go out in the community and say, 'Hey, would you give money so we can pay the electricity bill?'"

He pointed out the solar array, combined with soon-to-be-completed battery backup, will provide 53 kilowatts of power, enough to make the clinic officially net-zero in terms of carbon emissions.

The $165,000 grant from Direct Relief comes through the group's Power for Health Initiative, born amid the aftermath of Hurricane Maria in Puerto Rico.

Sara Rossi, managing director of the group's Health Resiliency Fund, said health providers' biggest need was to get the power back on.

"That could include making them more resilient to the effects of climate change through rooftop solar and battery backups that help them weather power outages," Rossi outlined. "Or helping them increase their ability to store cold chain medications and vaccines."

Bauermeister added Direct Relief's solar power system is a gift to their patients that will keep on giving.

"They were generous enough to give us a grant to install 135 solar panels on our roof," Bauermeister noted. "So far, we saved $8,249.87 and that will go on forever. We're forever going to save money on electricity."

Nebraska was among the states affected by the recent E. coli outbreak traced to onions in McDonald's hamburgers. Federal officials said they are now certain about the source but broader questions about the overlap with beef production linger.

The outbreak caused at least one death and sickened dozens of people. This week, key federal agencies closed the investigation, which pinpointed onions from a Colorado farm, while also ruling out burger patties. Ahead of the conclusion, some food safety experts wondered more about bacteria in manure from factory farms, where livestock is raised, finding its way to produce operations.

Prashant Singh, associate professor of health, nutrition and food science at Florida State University, explained the problem with having the different farming operations so close to each other.

"Manure, sometimes, if not properly processed in large operations, can spill over into a fresh produce area," Singh pointed out.

More specifically, contaminated dust particles from waste at concentrated animal feeding operations can land on fields of lettuce, for example, or get into irrigation canals. Separately, a California carrot company last month launched a voluntary recall because of an E. coli outbreak. Environmental groups noted many carrots in California are grown near factory farms.

Singh emphasized meat production has accelerated under evolving technology, with regulations enforced by the U.S. Department of Agriculture but produce is monitored by the Food and Drug Administration and he said the resources are vastly different.

"On the FDA side, they lack everything," Singh observed. "Their hands are very full. "

Even with the resource imbalance, other food safety experts note the meat lobby has focused heavily on avoiding strict regulations under the USDA, and existing laws have limits. Meanwhile, data from the Centers for Disease Control and Prevention show there have been nine multistate foodborne illness outbreaks in 2024.
