Federal health officials continue to investigate a summer outbreak of cyclosporiasis linked to iceberg lettuce, leaving consumers questioning the safety of eating lettuce. For now, the overall consensus suggests it is generally safe to consume, with important caveats, reports BritPanorama.
The US Food and Drug Administration (FDA) stated in a recent update that it “remains confident that all recalled iceberg lettuce related to this specific Cyclospora outbreak is off the market” and that such products should no longer be available in stores or restaurants.
While consumers need not completely avoid iceberg lettuce, they should remain cautious to avoid any items part of the initial recall and adhere to general food safety practices. Matthew Moore, an associate professor of food science at the University of Massachusetts Amherst, noted, “If today for dinner you wanted to go out and eat a salad, you’re pretty safe from cyclospora at this point, as far as we know.”
The FDA’s assertion that the recalled lettuce is off the market is critical for shoppers determining whether to purchase or consume lettuce. Dr. Jennifer Layden, associate dean for practice and a professor at the Bursky School of Public Health, confirmed, “Assuming you do not come across any food with a known recall, yes, it is OK to eat such types of produce.”
She emphasized that the implicated iceberg lettuce has been removed from the market, indicating that consuming the product is now safer. However, she advised those with such products at home to sanitize any surfaces or containers that came into contact with them.
This outbreak initially drew attention after data linked shredded iceberg lettuce to illnesses reported among individuals who had dined at select Taco Bell locations. The FDA traced the lettuce to Taylor Farms and growers in Mexico.
On July 17, Taylor Farms de Mexico declared the removal of all iceberg lettuce sourced from central Mexico from the US market and initiated a recall of Marketside iceberg salad packs along with shredded lettuce that had best-if-used-by dates from July 18 to August 3.
Dr. Colleen Kraft, a professor of infectious diseases at Emory University School of Medicine, stated, “I am comfortable with people eating iceberg lettuce that is currently being sold. I would distinguish between the specific recalled product and iceberg lettuce as a category.”
Are new cases still being reported?
According to the FDA and the US Centers for Disease Control and Prevention, the total number of reported illnesses linked to the outbreak has reached 11,458 across 20 states, which includes 495 hospitalizations and two fatalities. Notably, most of the reported cases started before the announcement of the Taylor Farms iceberg lettuce recall.
The FDA cautioned that newly reported cases might not represent newly acquired infections due to significant delays in symptom manifestation, diagnosis, and linkage to the outbreak. “This lag in reporting gives a false sense that cases are still occurring,” Dr. Layden noted.
What are safe alternatives?
Health experts encourage consumers to continue eating fresh produce, as fruits and vegetables are vital to a healthy diet. For those concerned about cyclospora, cooked vegetables present a lower-risk alternative, as cooking can eliminate pathogens. Additionally, peeling fruits such as bananas or oranges provides a protective measure.
Practicing safe food handling and proper hygiene is also crucial, including washing hands and fresh produce, avoiding cross-contamination, and discarding expired items. Dr. Layden emphasized that safe food practices are essential, particularly during this time of year when such outbreaks are more common.
When will the outbreak be over?
An ongoing investigation into the cyclospora outbreak will continue until health officials are confident that new cases no longer arise. According to Dr. Kraft, the investigation encompasses laboratory testing, patient interviews, and inspections of growers and processing facilities in Mexico. Although the immediate consumer risk appears to have diminished, the epidemiological inquiry remains active.
Experts expect that the outbreak could be declared over within weeks, noting that generally, an agency will close an outbreak when there are no confirmed cases associated with it for an extended period, coupled with assurance that the implicated product has been completely removed from the food supply.
As investigations proceed, the situation remains fluid, with health officials prepared to adapt their recommendations as new data becomes available.
