US FDA says it is investigating another cyclosporiasis outbreak

The US FDA is investigating a new cyclosporiasis outbreak involving 72 cases from an unidentified source, adding to a surge in cases across the US Midwest, including Michigan and Ohio. Cyclosporiasis is an intestinal illness caused by a parasite, typically spiking in warmer months. The CDC has confirmed 4,173 domestically acquired cases since May 1 and is investigating over 7,400 additional reported infections. Regulators have linked a broader outbreak in the Midwest to iceberg lettuce from a Taylor Farms plant in central Mexico, leading to a recall on July 17. However, Mexico states there is "no evidence yet" that its lettuce caused the US outbreak. The outbreak has also impacted restaurant operators, with Taco Bell ceasing to use Taylor Farms lettuce.
