Taylor Farms has voluntarily withdrawn all iceberg lettuce sourced from central Mexico from the US market, following a cyclosporiasis outbreak linked to shredded lettuce used by Taco Bell. The move matters because Taylor Farms is a major US produce supplier, and the outbreak highlights weaknesses in America's food safety tracing system at a time when regulatory oversight has been reduced. Taco Bell has already said it is removing the affected ingredient from its supply chain nationwide and will replace it within 24 hours in some states.

The lettuce in question was produced as five-pound bags at a Taylor Farms de Mexico facility in Guanajuato and distributed via Sysco. Cyclospora, the parasite behind the illness, causes symptoms such as watery diarrhoea, vomiting and flu-like aches, with an incubation period of one to two weeks. The FDA has traced the likely source to an independent farm representing under 1% of US iceberg lettuce supply, though tracing efforts have been hampered by staff cuts of over 240 consumer safety specialists and a delayed food traceability rule, now pushed back to 2028; the CDC is separately investigating unrelated illness clusters in other states.
