PITTSBURGH, PA. - Top researchers are in Pittsburgh today for a national conference taking a closer look at "off-label" chemicals used in much of the food packaging we use. The Rachel Carson Legacy Conference will investigate what are known as endocrine disrupting chemicals, or EDCs, which are used in many products, from insecticides to soda cans, but are not listed on the label. Concerns the chemicals can leach into food and drink have led to bans in Europe and Canada, while the U.S. Food and Drug Administration (FDA) says health effects are inconclusive. Scientists and industry representatives meeting today will discuss how to handle the chemicals more responsibly.

Fiona Fisher, spokesperson for the Rachel Carson Homestead Association, says EDCs are commonly found in the linings of food packages, drink cans and bottles.

"The manufacturers needed to find a way to stop the taste of the aluminum cans from blending in with the food, and this is one of the things they came up with."

Research also shows the chemicals not listed on a product label can, in some cases, be more dangerous than those that are, adds Fisher. It's a lesson that goes beyond food and drink, she says.

"One of the inert ingredients in a can of insect spray was actually more toxic than the active ingredients, so there really needs to be a lot more clarity and a lot more transparency in this area."

EDCs also pose a problem even after they're disposed of, she says.

"How can we recycle, taking the potentially harmful endocrine disrupting chemicals out versus dumping them all in a landfill where they'll never go away?"

Some research indicates EDCs tamper with hormones, especially in young children and those still in the womb, and may cause infertility, miscarriages and cancer. The FDA's findings on one EDC, Bisphenol A (BPA), have been inconclusive. Bills have been introduced in both the U.S. House and Senate to ban its use in food and beverage containers. BPA has been outlawed in both Europe and Canada.

The Rachel Carson Legacy Conference runs today Friday at the Bidwell Training Center in Pittsburgh.

Missouri may, at one time, have had a reputation as the "meth-lab capital of the country" - but a five-part podcast uncovers its true history.

"Home Cooked: A Fifty-Year History of Meth in America" delves into the relationship of methamphetamine use with broader drug policies and social and cultural ramifications.

Reporter Olivia Weeks with The Daily Yonder, who produced and hosts the podcast, said meth use was once associated with rural areas, but that assumption is inaccurate. Weeks said Missouri fought back against its meth-lab reputation.

"They policed their meth-lab problem really strongly, and had really high lab bust numbers and then those have basically disappeared," she said. "But now, the rest of the country is dealing with this problem that was associated with Missouri."

In the podcast, she explains that most of the methamphetamine entering the United States comes through commercial points of entry, hidden in legal shipping containers, rather than being smuggled across the border by individuals.

Weeks said the real dangers of meth result in part from it being outlawed. She explained that even when it was a prescription drug in the 1950s and '60s, there was illegal use - but at least it was made by pharmaceutical companies. Once methamphetamine became illegal, she said, the lack of control over its production has led to environmental damage and dangerous chemical processes being attempted in home labs.

"The main problem, main danger of using methamphetamine is that you don't know what's in it," she said, "and you don't know what dose you're taking."

She acknowledged the pharmaceutical industry's history of exploiting addictive drugs, and cautioned against a simple solution such as decriminalizing or legalizing meth use. Instead, she said, her research has prompted her to support harm-reduction strategies that keep users safe.

Minnesota is the site of a high-profile drinking-water contamination case linked with so-called forever chemicals and advocates are hopeful residents will be protected in the future by a new national standard announced Wednesday.

The Environmental Protection Agency unveiled a final rule which, for the first time, sets a legally enforceable drinking-water benchmark for PFAS chemicals all states will have to follow. Scientists have been highlighting health risks with more detection of PFAS in everyday products and water sources.

Avonna Starck, state director for Clean Water Action, said requiring near-zero levels sends a strong message.

"We've been hearing from polluters that it's too hard, it's too expensive, it's not feasible to stop using these chemicals," Starck pointed out. "This standard really said, 'No, actually this is something that we're gonna do, this is something that we can do.'"

There is some concern from operators of public water systems, who fret about costs to update facilities. However, officials noted there is federal funding to help with the transition. Minnesota recently adopted its own PFAS law, which emphasizes product bans, following a 2018 settlement with manufacturer 3M over claims its production of PFAS chemicals damaged drinking water and natural resources.

The subsequent state law was named in honor of Amara Strande, who died last year from cancer her family believes is linked to the toxic chemical waste from 3M. Her sister Nora said the new federal standard for drinking water is welcome news.

"PFAS is in the air, it's in the water, it's in our products, it's in our land," Strande outlined. "We need to work on this on multiple levels."

Under the new rule, the EPA estimated between 6% and 10% of 66,000 public drinking water systems around the U.S. may have to take action to reduce PFAS. All of them have three years to complete initial monitoring. If levels exceed the new standards, the systems must take corrective action within five years.

Nonorganic fruits and vegetables are loaded with chemical pesticides, including fungicides which can harm male reproductive systems, according to the 2024 Shoppers Guide to Pesticides in Produce.

Alexa Friedman, senior scientist for the Environmental Working Group, explained food is the primary way most people in Wyoming and across the nation are exposed to pesticides, which have been linked to a number of negative health outcomes.

"Things like cardio metabolic disorders, different types of diabetes, as well as some cancers," Friedman outlined. "If you are exposed to multiple pesticides over the course of a lifetime they might lead to a greater risk in any of these health outcomes."

Conventionally-grown strawberries top this year's Dirty Dozen list, followed by spinach, kale and collard and mustard greens, grapes, peaches, pears, nectarines, apples, bell and hot peppers, cherries, blueberries and green beans.

Fungicides, which can be endocrine disrupters and harm human hormone systems, are often applied after harvest to keep produce mold-free on its way to market. Most of the produce tested by the U.S. Department of Agriculture fell within the legal allowance for pesticide residue but Friedman argued "legal" does not necessarily mean "safe."

"Even if the amount of pesticides are within legal limits on these produce, it doesn't mean it's safe for everyone, particularly susceptible populations like children," Friedman stressed.

The shopper's guide also includes the Clean Fifteen, a list of fruits and vegetables with very low or no pesticide residues. Organic avocados, sweet corn and pineapple top the list.

Friedman encouraged people to continue to eat as many fruits and vegetables as possible, organic or conventional, due to their nutritional value compared with highly processed foods.

"We always recommend continuing to consume fruits and vegetables, and to up your fruit and vegetable intake," Friedman pointed out. "If you are interested in purchasing organic versions of the produce that's on the Dirty Dozen, there are also some more budget friendly options in the frozen aisles."
