The Food and Drug Administration along with the Centers for Disease Control and Prevention and state and local officials are currently investigating a massive salmonella outbreak across multiple states. According to a press release, Salmonella Poona was linked to “slicer” cucumbers produced by Andrew and Williamson Fresh Produce in Baja, Mexico.

There were illnesses linked to the cucumbers reported in 285 people in Alaska, Arizona, Arkansas, California, Colorado, Idaho, Illinois, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, New York, North Dakota, Ohio, Oklahoma, Oregon, South Carolina, Texas, Utah, Virginia, Washington, Wisconsin, and Wyoming. There has been one death related to the outbreak so far, and 53 people have been hospitalized.

Based on survey data taken from people suffering from salmonella infections, a significantly high number of the patients reportedly ate cucumbers before falling ill. The disease was not confined geographically, but investigators were able to connect all of the cases back to a common supplier.

State and agricultural departments have begun collecting cucumbers from grocery stores and restaurants where infections were reported, and extensive product testing is being carried out at Andrew & Williamson Fresh Produce. The company has issued a recall of all cucumbers sold between August 1, 2015 and September 3, 2015.

Symptoms of Salmonella include diarrhea, fever, and abdominal cramps. Infections can last up to a week, and most people recover with no treatment.
