The bad salad was served to unsuspecting patrons at Olive Garden and Red Lobster chain restuarants in the Midwestern states, and has been traced back to a Taylor Farms de Mexico, S. de R.L. de C.V. owned facility north of Mexico City, the only international farm owned by the California-based company.
Outbreaks have only been linked to Red Lobster and Olive Garden restaurants, owned by the Darden Restaurants group. There don't seem to be any problems with salads sold to consumers at grocery stores.
“It is not yet clear whether the cases reported from other states are all part of the same outbreak,” said the US Food and Drug Administration in a statement on the outbreak. "The investigation of increased cases of cyclosporiasis in other states continues.”
Although 400 people across 16 states have been sickened by cyclospora in recent weeks, it remains unclear if they are all part of the same outbreak, added the FDA. More research will be needed to establish a link.
Taylor Farms released its own statement on the outbreak, writing that the "health and safety of our customers is our number one priority. We can confirm statements by the Midwest health officials that products supplied during the month of June are no longer in the supply chain and bagged salad is safe to eat."
What is cyclospora? This nasty one-celled protazoan often is found in fresh produce, and can hit victims with debilitating symptoms, including diarrhea, nausea, cramps, and bloating, as well as considerable fatigue.
Unlike milder stomach bugs, a cyclospora attack can often last for weeks — as an unfortunate Texas teacher profiled by ABC found — and is often difficult to diagnose. Once caught, it is usually treated with antibiotics.
