(UPDATED COVERAGE, 1:55 p.m.) With 466 cases of cyclospora parasite infections already confirmed and more cases being confirmed daily, the Food and Drug Administration has stepped up its traceback investigation into the packaged salad mix from a Taylor Farms facility in Mexico.
The agency now has 21 people — up from five a week ago — on the case at its headquarters. FDA specialists in 10 field offices across the country are also working on the outbreak investigation. As of Aug. 5, infections from the tropical, one-celled parasite had been confirmed in 16 states, according to the Centers for Disease Control and Prevention.
Investigators with FDA have already confirmed that Iowa and Nebraska health officials were correct when they linked outbreaks in their states to packaged salad mix from Taylor Farms de Mexico, S. de R.L. de C.V.
“As a result of the current investigation FDA is increasing its surveillance efforts on green leafy products exported to the U.S. from Mexico,” according to the agency’s Aug. 6 update.
Investigators are trying to determine if outbreaks in 14 other states are also related to the salad mix, or if there is another potential source. The salad was served at Rod Lobster and Olive Garden restaurants, which are part of the Darden Restaurants operation.
Darden's communications director Rich Jeffers said Aug. 7 that the company is cooperating with investigators.
"We respect their findings and will continue to work with them on this matter. Iowa and Nebraska health authorities have said this is not an ongoing outbreak and the product is no longer in the food supply in those states," Jeffers said.
The FDA update said the implicated salad mix is likely out of the supply chain by now because of its limited shelf life.
