Salmonella Egg Recall, Cyclospora Outbreak Spread Across US

Federal health authorities are tracking two simultaneous foodborne illness outbreaks that have sickened more than 2,000 people across multiple states, as a massive egg recall over salmonella contamination coincides with the rapid expansion of a cyclospora outbreak linked to imported iceberg lettuce.

Background & Context

The twin outbreaks represent one of the most significant food safety challenges in the United States this year, affecting consumers across dozens of states and prompting recalls at major retailers including Kroger, Walmart, and Brookshire Grocery stores. Both the Centers for Disease Control and Prevention and the Food and Drug Administration are actively investigating the sources of contamination.

Salmonella Egg Recall

On July 22, Midwest Poultry Services, L.P. issued a voluntary recall of more than 1.5 million dozen eggs — approximately 19.1 million individual eggs — after proactive environmental monitoring detected contamination with Salmonella Enteritidis at its Texas farms, according to the FDA recall announcement. The recalled eggs, produced between June 6 and July 3, 2026, were sold under brand names including Kroger, Simple Truth, Brookshire’s, Country Morning, and Sunups.

As of July 24, the CDC has confirmed 98 cases across 17 states, with 26 hospitalizations — a 36% hospitalization rate among those with available information. Illnesses began as early as November 2025 and continued through June 2026. The states affected span from California to New York, including Arizona, Colorado, Georgia, Illinois, Louisiana, Michigan, Missouri, Mississippi, North Carolina, New Mexico, Nevada, Oklahoma, South Carolina, Texas, and West Virginia.

The salmonella strain involved is antibiotic-resistant, showing reduced susceptibility to ciprofloxacin and resistance to nalidixic acid. While most infections resolve without treatment, the CDC noted that if antibiotics are needed, some commonly recommended drugs may not be effective against this strain.

Cyclospora Outbreak

At the same time, a cyclosporiasis outbreak linked to shredded iceberg lettuce from central Mexico has become the largest reported in the U.S. this year, with at least 1,947 confirmed cases across nine states. The CDC reported 98 hospitalizations and no deaths as of July 24. The outbreak has expanded to include four newly linked states — Illinois, Kansas, Oklahoma, and Pennsylvania — joining Indiana, Kentucky, Ohio, West Virginia, and Michigan, which has been hit hardest.

Taylor Farms de Mexico initiated a recall of all iceberg lettuce sourced from central Mexico on July 17, after traceback investigations identified the company’s shredded iceberg lettuce as the likely source. The recalled products, including Marketside-brand items sold at Walmart and lettuce distributed to retailers such as Target and Whole Foods, were shipped across at least 27 states. Taco Bell, which received shredded iceberg lettuce from Taylor Farms, has stopped using the supplier. According to the FDA’s investigation page, the outbreak has also drawn attention to the challenges of detecting Cyclospora cayetanensis, a microscopic parasite not endemic to the U.S.

The response has not been without controversy. Mexican health authorities tested lettuce and water from Taylor Farms’ facility and reported negative results, though the FDA maintains that the company remains the likely source. Taylor Farms drew criticism for a confusing recall notice and a dispute over whether the FDA apologized for a false positive test result.

Analysis & Implications

With a combined total of more than 2,045 reported illnesses and at least 124 hospitalizations across two unrelated outbreaks, the parallel crises underscore persistent vulnerabilities in the U.S. food supply chain. As CNBC reported, the cyclospora outbreak has already surpassed the typical annual case count of 200 to 1,000, and health experts warn it is not yet under control. The actual number of cyclospora cases is likely higher than reported, as routine stool tests do not always screen for the parasite.

The antibiotic-resistant salmonella strain adds another layer of concern. The FDA’s Egg Safety Rule, finalized in 2009, was designed to reduce salmonella contamination in eggs, but this outbreak demonstrates that risks persist despite preventive measures.

The cyclospora outbreak, originating from imported Mexican produce, has also taken on political dimensions. President Trump was reported to have commented on imposing tariffs on Mexico in connection with the lettuce contamination, highlighting how food safety issues can intersect with trade policy.

What to Watch For

Both outbreaks remain under active investigation. The CDC anticipates case counts will continue to rise for the cyclospora outbreak due to the 3-4 week lag between illness onset and reporting. Consumers are urged to check their refrigerators for recalled eggs bearing plant codes P-1950 or 0840962 with Julian dates 157 to 184, and to discard any recalled iceberg lettuce from Taylor Farms de Mexico. Anyone experiencing symptoms of salmonella infection — including diarrhea, fever, and abdominal cramps — or cyclosporiasis — including watery diarrhea, fatigue, and loss of appetite — should contact a healthcare provider.

The FDA and CDC continue working with state and local partners to prevent further spread, while retailers have removed affected products from shelves. Whether these outbreaks prompt broader regulatory changes or increased scrutiny of imported produce remains an open question.
