Mexico ministries investigate cyclospora linked to Mexican farm

Mexico’s health and agricultural ministries have announced they are investigating a large outbreak of a foodborne illness in the US linked to iceberg lettuce grown in Mexico and sold at Taco Bell.

Cofepris, Mexico’s sanitary regulator, and Senasica, the country’s agricultural and food safety regulator, said in a statement Friday that they have an interagency technical working group investigating the matter and adopting preventive measures.

The group has undertaken inspections and traceability analyses that “are strictly preventive in nature” and “aimed at mitigating any potential health risk,” the agencies said.

The CDC has reported around 100 hospitalisations of people becoming sick with cyclosporiasis, a parasitic infection that can cause severe diarrhea and other gastrointestinal symptoms, after eating shredded lettuce at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia.

On Friday, Taylor Farms, a California-based lettuce supplier, and ​food distributor Sysco, America’s largest, said they are removing iceberg lettuce sourced from central Mexico, based on information provided by the US Food and Drug Administration (FDA).

An industry source who requested anonymity because they were not authorised to speak to the media told Reuters that the lettuce was produced as 2.3-kg bags at Taylor Farms' facility in Guanajuato, in central Mexico.

The source also said that Sysco widely distributes such bags to hospitals, ballparks, and fast-food chains.

Mexico’s health and agricultural ministries cautioned in their statement that "the investigation remains ongoing, and it is important to emphasise that identifying a product's country of origin through traceability does not, by itself, confirm that contamination occurred in Mexico."

Taylor Farms' growing and ‌processing facilities in ⁠Mexico were the source of another major US cyclosporiasis outbreak. A 2013 outbreak sickened more than 600 people in 25 states, according to the CDC, and was traced to salad mix from Taylor Farms de Mexico in Guanajuato.
