Salad, new public enemy number 1 in the United States? While cases of cyclospora contamination – a microscopic parasite present on certain vegetables – reach a record level in the country, psychosis is gripping the population. In the American press, articles are multiplying. “Can I still eat lettuce?” », even asks the Washington Post, while the Secretary of Health, Robert F. Kennedy Jr., declared Tuesday July 21, 2026 that the epidemic was “under control”.
As of early this week, more than 30 states had reported cases, with about 100 hospitalizations but no deaths. Nearly 1,700 cases contracted between May 1 and July 13 have been confirmed. Authorities indicate, however, that the actual number of infections is much higher, with Michigan, for example, reporting more than 6,500 probable cases as of July 16.
A gastrointestinal disease of still uncertain origin
Diarrhea, nausea, vomiting, cramps, fatigue, low-grade fever, etc. Cyclospora causes gastrointestinal illness through the ingestion of fruits or vegetables, particularly when they have been irrigated or washed with water infected with human stools. Generally not dangerous – except for the elderly, immunocompromised or pregnant women – it is not contagious between humans, and can be treated with antibiotics.
U.S. public health investigators are working to understand the origin of this massive outbreak. The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are investigating the possible involvement of iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. They gradually go back to a supplier located in Mexico, Taylor Farms of Mexico.
But on July 19, a new twist: the FDA announced that a sample of lettuce from Taylor Farms in Mexico was in fact a false positive. The next day, however, the institution clarified on
To clarify, this false-positive lab sample DOES NOT change the basis for FDA’s ongoing outbreak investigation or the overwhelming epidemiological data supporting the current voluntary recall by Taylor Farms.
Over the weekend, FDA alerted Taylor Farms that a new sample of… https://t.co/hedRwhPLd8

Social networks, a field of speculation
According to some critics, the public alert came too late. At issue: research on cyclospora which is only in its infancy (the parasite was only described for the first time in 1979) but also the budget cuts imposed by the government of Donald Trump which have hit health surveillance systems hard.
By the time the FDA pointed the finger at Taylor Farms, concerned consumers took to social media. “What state are you in and have you identified the foods you ate that could be the cause?” », asks one of them in a publication which records more than 1,300 responses. False accusations concerning several supermarkets or restaurants are also circulating. At the same time, a worrying digital trend is emerging: “#cyclosporaskinny” (contraction of cyclospora and slimming). In several viral videos, which encourage people to voluntarily ingest the parasite, cyclospora becomes an inexpensive “slimming remedy”.
Salmonella risks remain much greater
On Instagram, some are wondering if they should ban salad from their plate for a while. While health authorities emphasize the importance of washing fruits and vegetables as thoroughly as possible before consumption, only cooking can kill the parasite. Farms must resort to sophisticated and expensive methods such as microfiltration.
Faced with the situation, certain American salad producers are highlighting their “more closely monitored” production in the local press, without yet noticing an increase in demand. However, in a country where nearly 40% of children believe that hot dogs are vegetables (according to a study published in 2021 by Furman University, in South Carolina), we must “not stop eating fruits and vegetables because of cyclospora,” insists the Washington Post. And this new contamination is not particularly widespread compared, for example, to salmonella, which is the cause of approximately 1.35 million cases of intestinal illness each year in the United States.
