The FDA announces an outbreak of stomach illnesses in Iowa and Nebraska is linked to salad mix served at Olive Garden and Red Lobster restaurants in those states and supplied by a Mexican farm.
The outbreak of cyclospora infections has sickened more than 400 people in 16 states in all.
The FDA says it is working to determine whether the salad mix is the source of illnesses in the other 14 states.
“It is not yet clear whether the cases reported from other states are all part of the same outbreak,” the FDA said in a statement.
“The investigation of increased cases of cyclosporiasis in other states continues.”
Both Olive Garden and Red Lobster are owned by Orlando-based Darden Restaurants. In a statement, Darden spokesman Mike Bernstein said the FDA’s announcement is “new information”.
“Nothing we have seen prior to this announcement gave us any reason to be concerned about the products we’ve received from this supplier,” Mike Bernstein said.
The FDA said it traced illnesses from the restaurants in Nebraska and Iowa to Taylor Farms de Mexico, the Mexican branch of Salinas, California-based Taylor Farms.
Taylor Farms, which provides produce to the food service industry, said its facility located about 180 miles north of Mexico City in San Miguel de Allende is the only one of its 12 sites to be connected to the cases.
The salad mix in question includes iceberg and romaine lettuce, as well as red cabbage and carrots, according to officials.
In a statement on the company’s website, Taylor Farms says the Mexican facility is “state of the art and has an exceptional food safety record”.
The statement said the company is working with FDA investigators who are looking at the facility and that the product is out of the food supply.
The FDA said its investigation has not implicated packaged salad sold in grocery stores.
The salad mix may be out of the commercial food chain as the most recent known illness in those two states was in Nebraska a month ago.
The typical shelf life for a salad mix is up to 14 days.
There have been more recent illnesses in other states.
According to the Centers for Disease Control and Prevention (CDC), the most recent illness was July 23.
Cyclospora is transmitted through raw fruit and vegetables by leaving it’s droppings on fruit and vegetables, according to health officials who have said rinsing food isn’t enough to rid it of the problem.
The cyclospora parasite causes the intestinal illness cyclosporiasis if people eat or drink contaminated food and water.
Symptoms include nausea, diarrhea, abdominal pain, cramping, flu-like aches and pains, and a low-grade fever.
Health officials have said diarrhea can last nearly two months.
