Urgent Warning: Former FDA Food Safety Chief Advises Skipping Bagged Salads Amid 'Astonishingly Large' Cyclospora Outbreak

Imagine reaching for that convenient bag of pre-washed salad greens, only to be met with a stark warning from someone who knows the ins and outs of food safety better than most. That's exactly the message Susan Mayne, Ph.D., the former head of the FDA's food safety division, delivered recently: perhaps it's best to skip those pre-packaged greens for now.

Dr. Mayne, who led the FDA's Center for Food Safety and Applied Nutrition from 2015 to 2023 and now holds an adjunct professorship at the Yale School of Public Health, didn't mince words during her CBS News interview. She described the current cyclospora outbreak as "astonishingly large" and truly "record-setting," adding, "We've never seen anything like this." Her rationale for advising against bagged salads is straightforward, if unsettling: a tiny bit of contamination can easily spread much more broadly once greens are pre-cut and mixed in a bag. It's just too easy for a few tainted leaves to compromise the entire package.

So, what exactly are we up against? The culprit is a microscopic parasite called Cyclospora cayetanensis. And believe me, you don't want to get acquainted with it. Infections, known as cyclosporiasis, lead to prolonged and deeply unpleasant bouts of watery diarrhea, severe abdominal cramping, and a pervasive fatigue that can just linger and linger. It's not a quick bug; it can really knock you off your feet for an extended period.

The numbers are, frankly, unsettling. As of late July, over 4,173 confirmed cases of cyclosporiasis have swept across nine states in the U.S. since May, with another 7,400 suspected cases under investigation. This isn't just a minor blip; it's a significant public health concern that has food safety officials scrambling to identify the precise source.

The investigation is ongoing, and it's proving to be quite a challenge to pinpoint exactly where this parasite is coming from. While lettuce, parsley, and cilantro are among the top suspects, the FDA believes the largest current cluster of infections, affecting nine states, originated from contaminated iceberg lettuce from Mexico. This lettuce was distributed nationwide by Taylor Farms, a major supplier. Taylor Farms did issue a voluntary recall of shredded iceberg lettuce from Central Mexico, but honestly, the whole situation has been a bit of a mess from a communication standpoint.

And if you're feeling a bit confused about the situation, you're certainly not alone. The recall associated with this particular cyclospora outbreak has been described as "fraught with confusing messaging." At one point, the FDA updated its findings to suggest lettuce not part of the recall had tested positive, only to then delete that line, stating it was a false positive. Meanwhile, Taylor Farms itself stated on its website that "FDA has not identified a single positive product test result for Cyclospora," even while the recall remained in effect. It's enough to make your head spin!

This isn't the first rodeo, either. Back in 2020, over 700 cyclosporiasis cases across 14 states were linked to Fresh Express bagged salad kits. That investigation came tantalizingly close to a source, finding the Cyclospora pathogen in canal water, which many experts considered a key breakthrough in understanding how these outbreaks spread.

Even former FDA Commissioner Scott Gottlieb, M.D., weighed in on the broader implications, noting that it's "not standard operating procedure" for a company like Taylor Farms to reportedly seek White House intervention or delay a recall announcement. While he commended the current administration's efforts to isolate and identify the pathogen, he cautioned that the spread isn't "under control yet." A CBS News poll, in fact, highlighted public concern, showing that the outbreak has many people changing their eating habits, and revealed a mixed, even partisan, confidence in the FDA's handling of the crisis.

So, what's a savvy shopper to do in the face of such a widespread and perplexing outbreak? Dr. Mayne's advice is clear: for now, err on the side of caution and consider skipping those convenient bagged salads. Perhaps it's a good time to go for whole heads of lettuce or other greens you can wash thoroughly yourself, just to be on the safe side.
