In a concerning health update, Jefferson County has reported two additional cases of cyclosporiasis bringing the total to three for the year. This parasitic infection, known for causing nausea, stomach pain, and prolonged diarrhea has health officials on high alert.

The first case this year was linked to travel outside the area, but the two newest cases are not. Lisa Lagos, Jefferson County Public Health Educator, noted that one case occurred earlier in the spring and was travel-related, while the two newer cases are not.

Challenges in Tracing the Source

Pinpointing the source of cyclosporiasis is particularly challenging due to its incubation period. The parasite can take up to two weeks to manifest, with an average of one week. This makes it difficult for individuals to recall their activities and dietary habits from that period.

“For cyclosporiasis it can take up to two weeks, with an average of one week, and that’s a lot harder for people to recall what they’ve had for the last 10 days,” Lagos explained. “Not just what they’ve eaten but where they ate it, what the brand was, where they purchased it from.”

To aid in tracing the source, public health officials utilize electronic tools to help patients remember their consumption habits. “Thankfully, there are a lot of electronic resources that we can use to try to help pinpoint and help patients remember what they had to eat,” Lagos said.

Contextualizing the Outbreak

The two new cases in Jefferson County may or may not be connected to a nationwide outbreak. Health officials noted that the current count is not out of the ordinary. In 2026, the county recorded nine confirmed cases, and four cases each in 2026 and 2026.

The New York State Department of Health reported approximately 576 cases in New York since May 1st. They emphasized that the current cases statewide do not represent a “major deviation” from the norm. “While cyclosporiasis is generally not life-threatening, as many people with healthy immune systems recover without treatment, the Department encourages all New Yorkers to be aware of the best practices to prevent cyclosporiasis and other infections common in the summer months,” a spokesperson stated.

National Investigation and Consumer Reactions

At the national level, the Food and Drug Administration (FDA) initially confirmed that a lettuce sample supplied by Taylor Farms in Mexico tested positive for cyclospora. However, the FDA later stated that this result should be considered a false positive, though they continue to investigate a potential link.

Despite the outbreak, New York City shoppers and grocery store employees reported that it has not significantly affected their purchasing habits. However, many expressed concern over the lack of clarity about the outbreak’s origin and the products most responsible.

Sam Watson, a shopper in Brooklyn, shared her approach to food safety during the outbreak. “I feel like it’s not crazy concerning,” Watson said. “We haven’t really changed too much about our food purchasing, just being extra careful to wash everything, like, three times with vinegar and baking soda [as] my mom said.”

Marc Plaskett, another shopper, decided to forgo his usual arugula and spinach blend to avoid potential exposure. “I’m just taking my vitamins and I’m avoiding greens,” he said. “I don’t want to really be an experiment. I don’t want to test out the different lettuces and find out the hard way, and then I end up with the parasite.”

Thomas Gremillion, director of food policy for the Consumer Federation of America, criticized Taylor Farms’ recall list and details for being confusing and ambiguous. “Taking this recall notice and communications at face value if you are a consumer in New York, there’s not, not anything you need to do,” Gremillion said. “However, for folks wanting to be cautious, at this point, I’d be comfortable telling people maybe just avoid Taylor Farms.”
