Most people probably assumed that when the headline said “lettuce recall,” it was just another one of those contained, controllable food scares, the kind that are resolved in a week or two and only involve one company. The director of the CDC from 2018 to 2021, Dr. Robert Redfield, is speculating that it may be much more complex than that.
Redfield expressed worries that go far beyond iceberg lettuce in a recent interview with NewsNation. He added that blueberries, raspberries, and snow peas have also been found to harbor the parasite cyclospora. That’s a significant change in how this outbreak should be perceived, and it’s the kind of information that often gets overlooked in favor of the more immediately concerning case counts.
Even by themselves, those figures are noteworthy. The CDC reports that over 22,000 cases of cyclosporiasis have been confirmed or are being investigated nationwide. With over 11,000 confirmed cases and the nation’s first two reported deaths connected to the outbreak, Michigan has emerged as the hardest-hit state. Health officials confirmed that both individuals had serious underlying medical conditions. Fifteen states are now formally tied to the investigation, with the primary source traced to iceberg lettuce grown in central Mexico and distributed by Taylor Farms, though Taylor Farms has said its own testing found no positive results for the parasite.
Things become truly uncertain at that final point. Redfield expressed his doubts to NewsNation about the lettuce’s ability to fully explain the outbreak’s scope.
As you listen to him talk, you get the impression that he’s trying to convey something that the official investigation hasn’t yet fully grasped. Cyclospora public health traceback is infamously challenging because symptoms usually don’t show up for a week or longer after exposure, so by the time a person is sick enough to visit a doctor, they frequently have forgotten exactly what they ate.
What happens when you try to wash contaminated produce is one of the more disturbing things Redfield described. It is ineffective. The parasite is not washable. “If you wash your lettuce and you put it in a lettuce spinner and you have cyclospora in that lettuce, it’s still going to be there,” he replied. That’s not a hypothetical — it’s the biological reality of how this particular pathogen behaves on produce surfaces, and it changes the calculus for anyone standing in a grocery store trying to make a safe choice.
He was pretty straightforward in his practical advice: buy locally. Imported produce — particularly from regions where irrigation or handling practices may expose crops to human fecal contamination — carries the higher risk here. He believes that during an outbreak like this one, locally grown fruits and vegetables from neighboring farms are much safer. Produce with thick, inedible peels offers some additional protection, and anything cooked to 158 degrees Fahrenheit would eliminate the parasite, though that doesn’t help much with a summer salad.
It’s also important to understand that cyclosporiasis is curable. Redfield was unambiguous about this. The antibiotic trimethoprim-sulfamethoxazole — sold under brand names like Bactrim and Septra — can significantly shorten recovery time, bringing what might otherwise be two to four weeks of illness down to five to seven days. The problem is that many people, particularly in the early stages, may not even associate their symptoms with a parasite. The symptoms include prolonged watery diarrhea, fatigue, bloating, cramping in the stomach, and weight loss. If symptoms worsen or persist for more than a few days, the CDC recommends consulting a physician.
Even a month ago, the number of open cyclospora investigations with the FDA would have seemed out of the ordinary. Today, there are seven. It’s still unclear if they all represent distinct contamination events in various areas of the food supply or if they are all related. What is evident is that there is still potential for this outbreak to spread, and those who are familiar with how these situations typically play out advise being cautious when importing raw produce, at least for the time being.
