Cyclospora Outbreak Affects Consumer Habits in the U.S.

An outbreak of Cyclospora linked to recalled iceberg lettuce is causing changes in consumer behavior across the United States. A recent poll by CBS News/YouGov indicates an increase in food safety concerns, leading many Americans to reduce their fresh produce purchases.

Impact on Produce Consumption

The survey reveals that 40% of Americans are eating or buying less produce due to the outbreak, while only 4% report purchasing more. Public anxiety is evident as federal health officials are investigating multiple clusters of the intestinal illness and warning consumers against recalled products.

The outbreak has been traced back to iceberg lettuce produced by Taylor Farms. A report from the Centers for Disease Control and Prevention (CDC) on July 24 stated that at least 1,947 people from nine states have been affected, leading to 98 hospitalizations but no deaths. Other, unrelated Cyclospora outbreaks are also under investigation nationwide.

Consumer Survey Insights

Conducted between July 22 and July 24, the CBS News/YouGov survey involved 2,193 U.S. adults and has a margin of error of 2.7 percentage points. It shows widespread awareness of the Cyclospora outbreak:

• 61% of respondents are following news about Cyclospora at least somewhat closely, with 18% following very closely and 43% somewhat closely.
• 40% report reducing their fresh produce consumption or purchases.
• 56% report no change in their shopping habits.
• 4% report buying or eating more produce.

Public confidence in the Food and Drug Administration (FDA), responsible for food safety, remains mixed. Only 13% of respondents expressed “a lot” of confidence, while 40% reported “some” confidence. Nearly half showed either “not much” confidence or no confidence in the FDA’s food safety oversight.

Details of the Outbreak

The outbreak is concentrated around iceberg lettuce from central Mexico, distributed by Taylor Farms, which issued a voluntary recall on July 17. The nine affected states are:

• Illinois
• Indiana
• Kansas
• Kentucky
• Michigan
• Ohio
• Oklahoma
• Pennsylvania
• West Virginia

Though no Taylor Farms products have tested positive for Cyclospora as of July 24, the company has recalled the implicated products and halted all sourcing and production of iceberg lettuce from central Mexico as a precaution.

Since May 1, the CDC has documented 4,173 confirmed domestic cases of cyclosporiasis, with over 7,400 additional suspected cases demanding further investigation.

Understanding Cyclospora

Cyclospora cayetanensis is a microscopic parasite infecting the small intestine and causing cyclosporiasis.

Transmission: People typically contract Cyclospora via food or water contaminated with fecal matter. Fresh produce like leafy greens, herbs, and berries are common vectors, linked to poor sanitation or contaminated irrigation water.

Contagion: Unlike many foodborne illnesses, Cyclospora is not passed directly from person to person. The parasite needs time in the environment to reach an infectious state.

Symptoms: Symptoms can appear 2-14 days after exposure. These include watery diarrhea, appetite loss, weight loss, stomach cramps, bloating, increased gas, nausea, and fatigue. Vomiting and mild fever may also occur.

Treatment: Healthy individuals usually recover with appropriate antibiotic therapy. Untreated infections can last for weeks or months with recurring symptoms.

Taylor Farms Response

Taylor Farms acted quickly after the outbreak’s source was identified. They recalled all their lettuce products available in retail stores and food service venues. A company spokesperson stated, “We prioritize the safety of our food and maintain robust prevention protocols for Cyclospora.”

The company highlighted that despite the lack of confirmed positive results for Cyclospora as of July 24, they have taken preventive actions, suspending all iceberg lettuce operations in central Mexico.

Taylor Farms has engaged independent experts to review food safety processes in their Mexican facility, continuing collaboration with health authorities and partners to address concerns.

CDC Recommendations for Consumers

Federal health officials advise the following:

• Check and discard any recalled Taylor Farms iceberg lettuce items from your refrigerators.
• Thoroughly clean countertops, cutting boards, and utensils that may have been in contact with the recalled lettuce using hot, soapy water or a dishwasher.
• Seek medical advice if experiencing prolonged gastrointestinal symptoms after eating fresh produce.
