Chow line: Salad recall prompts questions of parasite

I read something about a salad recall due to cyclospora, but I’ve not really heard about cyclospora before – what is it?

Cyclospora cayetanensis is a microscopic parasite that can cause diarrhea, stomach cramps, nausea, and fatigue. When people eat food or drink water that’s contaminated with cyclospora, they can develop an intestinal illness called cyclosporiasis.

The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention announced June 19 that they are investigating a multistate outbreak of cyclospora potentially linked to ALDI Little Salad Bar Brand Garden Salad from ALDI grocery stores, Hy-Vee Brand Garden Salad from Hy-Vee grocery stores, and Signature Farms Brand Garden Salad from Jewel-Osco. 

As of now, the recalled salad has not been sold in Ohio, but in stores locations in Arkansas, Iowa, Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, South Dakota, and Wisconsin. However, the FDA said, “it is continuing this investigation and there may be additional retailers and products impacted by this outbreak.”

Thus far, at least 122 people across seven states have been sickened after consuming the salad mix, with at least 19 people hospitalized, FDA said.

According to the CDC, cyclospora is generally transmitted when food or water is contaminated by infected feces, noting that the parasite is, “unlikely to be transmitted directly from person to person because it needs several days to weeks after being passed in a bowel movement to become infectious for another person.”

“Some people may experience symptoms that last a few days to a month or longer,” said Sanja Ilic, the state food safety specialist for Ohio State University Extension. OSU Extension is the outreach arm of The Ohio State University College of Food, Agricultural, and Environmental Sciences (CFAES).

Cyclosporiasis affects an estimated 15,000 people in the United States each year, according to the Cleveland Clinic.

Cyclospora infects the small intestine and usually causes watery diarrhea, with frequent, sometimes explosive, bowel movements. Other common symptoms include loss of appetite, weight loss, stomach cramps or pain, bloating, increased gas, nausea, and fatigue. 

People may also experience vomiting, body aches, headache, low-grade fever, and other flu-like symptoms, according to the CDC. Some people who are infected with the parasite don’t have any symptoms. If needed, treatment can include an antibiotic.
