Unregulated chemical 13,000 times sweeter than sugar is used in most e-cigarettes: study
A little-known artificial sweetener that's up to 13,000 times sweeter than sugar is now used in most popular flavored e-cigarettes — even though it is not listed on labels and is only FDA-approved for food, a new study found.
Neotame was detected in 57 of 73 flavored vaping products often marketed to kids and teens and had an average content nearly five times higher than in a mint candy, a study conducted by researchers from Yale School of Medicine and Duke University found.
Little is known about the health effects of inhaling the potent, no-calorie alternative, which was created by NutraSweet and is also known as Newtame, and current regulations do not limit its use, according to the June 2 study published in the Journal of the American Medical Association.

The researchers set out to prove, mainly to regulators and clinicians, how commonly the chemical, which is also up to 65 times sweeter than aspartame, is being used in newer products, they said.
All popular disposable e-cigs introduced after 2021 that haven't yet received U.S. Food and Drug Administration marketing authorization — 27 devices across 11 different brands — contained neotame, according to the study.
Among them were vapes from brands like Breeze Smoke, Elf Bar and Vapetasia, which offer flavors like Strawberry Apple, Killer Kustard and Blue Razz Ice.
Products from three brands — Vuse and NJOY, which are FDA-approved, and JUUL, which is awaiting approval — that were introduced before 2021 do not contain it, the study found.
The substance was likely chosen for its heat stability compared to other sweeteners, but its behavior when heated and vaporized in e-cigarettes is unknown, the scientists wrote in their findings.

'There are two specific concerns about the finding: How does it affect the potential for addiction to the product, and what are the product's adverse health effects when inhaled?' said Hanno Erythropel, the paper's lead author.
'Eating versus inhaling something is very different,' Erythropel, a Yale researcher, added. 'There are many examples in which chemicals are safe for eating but not for inhalation.'
Neotame is approved by the FDA for use in food, but not in vaping products, according to the researchers. When eaten in foods like cakes, soft drinks and chewing gum, neotame can seriously damage gut health, a study published last year in the medical journal Frontiers found.

'The respiratory and systemic health effects of neotame and its potential decomposition products during heating in an e-cigarette are unknown,' the scientists said.
Alarmingly, most of the 'funky' flavors used in e-cigarettes have not been evaluated for use in products other than food, Erythropel added.
The team hopes its findings pave the wave for further studies on neotame toxicity and exposure once it is heated and inhaled, and how users rate the appeal of e-cigarettes that contain it.

Salmonella outbreak linked to eggs sickens dozens of people across 7 states
More than 70 people across seven states have been sickened due to a salmonella outbreak linked to eggs recalled by a California-based egg distributor, according to the US Centers for Disease Control and Prevention. On Friday, the August Egg Company recalled 1.7 million dozen brown cage-free and brown certified organic eggs, sold under multiple brand names, that have the 'potential to be contaminated,' according to a recall notice from the US Food and Drug Administration. Of the 79 people sickened, 21 people have been hospitalized and no deaths have been reported, the CDC said. The eggs were sold to restaurants and retailers in Arizona, California, Illinois, Indiana, Nebraska, New Mexico, Nevada, Washington and Wyoming, according to the CDC. They were distributed at retail locations including Walmart, Save Mart, FoodMaxx, Lucky, Smart & Final, Safeway, Raleys, Food 4 Less and Ralphs. Salmonella can 'cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems,' according to the FDA. Salmonella can also cause fever, diarrhea, nausea, vomiting and abdominal pain in healthy people who get infected. 'August Egg Company is not selling fresh shell eggs at this time. Our firm has voluntarily been diverting eggs to an egg-breaking plant for over 30 days, which pasteurizes the eggs and kills any potential foodborne pathogens,' the company said in a statement provided to the FDA. 'It is important to know that when our processing plant identified this concern, we immediately began diverting all eggs from the plant to an egg-breaking facility, which pasteurizes the eggs and kills any pathogens.' The company also said its internal food safety team is 'conducting its own stringent review' to identify future preventative measures. 'We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again,' the company said. The CDC recommends that anyone who has the recalled eggs in their home or business throw them out or return them to the store where they were purchased.

Bedner Growers tied to salmonella outbreak: See which cucumbers are recalled
Twenty-six people have been sickened, with nine of them being hospitalized, due to a salmonella outbreak linked to cucumbers sold across the country. Now some cucumbers are being recalled. Cucumbers grown by Florida-based Bedner Growers and distributed by Fresh Start Produce Sales are linked to a salmonella outbreak, the Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) said in notices published May 19. As part of a follow-up inspection in April 2025, FDA investigators collected an environmental sample from Bedner Growers that tested positive for salmonella and matched recent clinical samples from ill people. No deaths have been reported so far, according to the FDA. Here's what to know about the recall and outbreak. Salmonella outbreak linked to cucumbers: More than 20 sickened in 15 states Bednar Growers is voluntarily recalling cucumbers sold at Bednar's Farm Fresh Market between April 29 and May 14, 2025. The cucumbers were sold directly to consumers at the three Bedner's Farm Fresh Markets locations in Florida (Boynton Beach, Delray Beach, and West Palm Beach). The FDA says the cucumbers may have been sold "individually or in smaller packages," with or without a label that may not bear the same brand, product name, or best by date. The vegetables were also sold to retailers, distribution centers, wholesalers, and food service distributors this spring. The agency did not identify specifically where the cucumbers were sold. According to the FDA, the products were labeled as either being "supers," "selects," or "plains" for distributors, restaurants and retailers who purchased the cucumbers. "Do not sell or serve whole cucumbers grown by Bedner Growers Inc. and distributed by Fresh Start Produce Inc. between April 29, 2025 to May 19, 2025," the FDA wrote. According to the FDA, if you have cucumbers at home and can't tell where they are from, throw them away. When eating out over the next week, consumers should ask if cucumbers were from Bednar Growers or Fresh Start Produce Sales Inc. Additionally, the FDA recommends washing surfaces and items that may have touched cucumbers using hot soapy water or a dishwasher. Businesses should not sell or serve cucumbers grown by Bednar Growers and distributed by Fresh Start Produce Inc. between April 29 and May 19, 2025. The FDA also recommends businesses wash and sanitize items and surfaces that may have come in contact with cucumbers, and stores should notify customers who may have purchased cucumbers using signs in stores or emails. As of May 20, the salmonella outbreak linked to cucumbers has sickened 26 people in the following 15 states: Alabama California Colorado Florida Illinois Kansas Kentucky Michigan North Carolina New York Ohio Pennsylvania South Carolina Tennessee Virginia According to the FDA, illness usually occurs within 12 to 72 hours after eating food that is contaminated with salmonella, and the symptoms usually last four to seven days. Symptoms include diarrhea, fever, and abdominal cramps. Children younger than five, the elderly, and people with weakened immune systems are more likely to have severe infections, the FDA says. Contact your healthcare provider immediately if you think you may have symptoms of a salmonella infection. Natalie Neysa Alund is a senior reporter for USA TODAY.

FDA: More cucumbers, ready-to-eat products recalled in growing salmonella outbreak
A Maryland food company has recalled specific salsa and cucumber products because they were made with cucumbers that are possibly contaminated with salmonella. TGD Cuts, LLC of Jessup, Maryland, is recalling some tub and tray products because they contained cucumbers from Boynton Beach, Florida-based Bedner Growers Inc., which have been linked to a salmonella outbreak. TGD Cuts distributed the affected products, which included salsas, sliced cucumbers and cucumber spears, to retail and foodservice locations in Maryland, Virginia, Pennsylvania, New Jersey, and North Carolina, according to the Food and Drug Administration (FDA). The products had use-by dates ranging from May 20 to May 28 and are unlikely to be in stores or being used. No illnesses have been reported in connection with the products, the FDA said. Egg recall: Brown eggs sold at some Walmart stores have salmonella risk The initial May 19 recall involved cucumbers sold directly to consumers at Bednar's Farm Fresh Market, according to notices published May 19 by the Centers for Disease Control and Prevention (CDC) and the FDA. Subsequent recalls have been announced by grocers such as Harris Teeter, Kroger and Walmart for repackaged cucumbers for resale under different brand names or those used in ready-to-eat products, including vegetable trays and salads. The cucumbers, distributed by Fresh Start Produce Sales of Delray, Florida, also led to Target recalling individual cucumbers on May 30, specifically cucumber two-packs and various prepared foods products. In addition to the growing cucumber-related recall, other products have been recalled recently for potential salmonella contamination. The FDA on May 28 upgraded a recall of tomatoes distributed in three southern states to a Class I recall, meaning consumption of the food could cause serious health complications or lead to death. Then, on June 6, the CDC and FDA linked brown eggs sold in nine states – including at some Walmart stores – to an ongoing Salmonella Enteritidis outbreak, in which 79 people have been sickened and at least 21 hospitalized. Customers who purchased any products from TGD Cuts should get rid of them or return them for a full refund. Here is the list of products recalled due to a possible salmonella risk. Item UPC Use By Date Salsa, Hot 6/12 oz. 840219170534 5/25/2025 Salsa, Mild 6/12 oz. 840219170541 5/25/2025 Salsa, Mild 5lb. 840219140445 not available Salsa, Mild 5lb. 840219140445 5/28/2025 Cucumber Sliced/Grape Tomato 50/2 oz. 840219184784 5/23/2025 Cucumber Sliced Unpeeled 5lb. 840219160733 not available Cucumber Sliced Unpeeled 50/2 oz. 840219170657 5/19/2025 Cucumber Spears 50/2 oz. 840219179971 5/19/2025 Salmonella poisoning causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths each year in the U.S., according to the CDC and FDA. Symptoms, which include diarrhea, fever and stomach cramps, will usually occur six hours to six days after exposure and may last up to seven days. Symptoms from severe infections may include aches, headaches, elevated fever, lethargy, rashes, and blood in urine or stool. Mike Snider is a reporter on USA TODAY's Trending team.
