The US Food and Drug Administration (FDA) along with the Centers for Disease Control and Prevention (CDC) have advised consumers to avoid purchasing certain onions due to a Salmonella outbreak that has caused at least 892 illnesses and 183 hospitalisations in 38 states and Puerto Rico. Several companies have recalled whole yellow, red, and white onions that were supplied by ProSource Produce LLC and Keeler Family Farms and imported from the State of Chihuahua, Mexico, between July 1 and August 31, according to a CDC news release.

The FDA said some of Green Giant Fresh’s whole yellow and white onions, as well as onions in certain meal kits from EveryPlate and HelloFresh were among those being recalled due to potential contamination.

People have been advised to contact their healthcare provider immediately if they develop any severe Salmonella symptoms. These include diarrhea and a fever higher than 102°F, diarrhea for more than 3 days that is not improving, bloody diarrhea, extreme vomiting, or signs of dehydration, such as dry mouth and throat and feeling dizzy when standing up.

However, most people will recover in four to 7 days.

The outbreak may not be limited to the states that have been listed by CDC as many people recover without medical care and are not tested for Salmonella.
