North Carolina Cyclospora Cases Likely Unrelated to Taco Bell Outbreak

Health authorities in North Carolina have reported that they do not suspect the recent cyclospora cases in the state are linked to the Taco Bell outbreak. This conclusion comes from a July 21 press conference, where officials noted multiple sources likely contributed to the increase in cases. Although the outbreak tied to shredded lettuce at Taco Bell continues, North Carolina health officials emphasize various origins for the cases.

Throughout June and July, cyclospora numbers have risen, with this year’s figures higher than usual. Carl Williams from the North Carolina Department of Health and Human Services stated, ‘There are many fresh fruits and vegetables that can serve as vehicles for cyclospora.’ It’s believed there are ‘multiple vehicles for cyclospora,’ indicating no single product or company involvement.

Despite significant connections to shredded lettuce in Michigan, North Carolina’s rise in cases suggests diverse sources. Williams pointed out that lettuce, parsley, and cilantro often appear in cyclospora cases but clarified that this doesn’t unequivocally assign blame.

A cyclospora outbreak affected the U.S. this summer, with CDC data showing 4,173 confirmed cases and 308 hospitalizations across 41 states since May 1. North Carolina alone reported 561 cases since May, with 254 occurring between July 14 and 21.

Understanding Cyclospora

Cyclospora cayetanensis is a microscopic parasite causing cyclosporiasis. Symptoms include watery diarrhea, stomach cramps, nausea, fatigue, and loss of appetite. It spreads through contaminated food or water. Humans remain the only known hosts.

Symptoms usually appear one to two weeks after exposure. Unlike many foodborne diseases, person-to-person spread is rare; the parasite requires environmental exposure to become infectious.

Fresh produce often becomes implicated in outbreaks because environmental factors, like irrigation, can contaminate fruits and vegetables.

The North Carolina Department of Health advises discarding damaged produce portions, rinsing before peeling, gently rubbing under running water, scrubbing firm produce with a clean brush, and drying with a clean cloth or paper towel.

CDC Broadens Outbreak States to Nine

The cyclosporiasis surge marks the largest outbreak of the illness in recent U.S. history. Previously, the CDC identified cases in Michigan, Ohio, Indiana, Kentucky, and West Virginia. Now, additional cases in Illinois, Kansas, Oklahoma, and Pennsylvania have possibly joined the outbreak, requiring further investigation.

Health Secretary Robert F. Kennedy Jr. remarked the outbreak was ‘under control,’ noting a federal investigation identified the source and triggered a lettuce recall. However, a Taylor Farms sample tested falsely positive for the parasite, highlighting issues in test accuracy. Mexico’s Health Minister David Kershenobich stated no evidence ties Mexican lettuce to the outbreak, though precautionary measures continue.
