If you have any apples in your home, ask the store where you purchased them if it uses Bidart Bros. in California as one of its suppliers. The Food and Drug Administration confirms that “two strains of Listeria monocytogenes were found at the apple processing facility.”

Specifically, Gala, Granny Smith and caramel apples have been affected by the listeria, and the recall is for those types of apples only. They can be sold under the brand names “Big B” and “Granny’s Best,” but they can also be sold under “other brand names or with no brand at all.”

The FDA says “consumers who are buying or have recently bought Granny Smith or Gala apples should ask their retailers if the apples were supplied by Bidart Bros.”

Reuters reports that seven people have died from the listeria outbreak, and 25 others were sickened between October and December of last year. The majority of those affected became ill after eating caramel apples, but the listeria was traced back to the Bidart Bros. plant and also came in contact with the Gala and Granny Smith apples.

The last of the contaminated apples were shipped on Dec. 2 and could still be on store shelves or in consumers' kitchens.

Food poisoning from listeria is called listeriosis, according to WebMD, and it affects the body in several ways:

Listeriosis affects mainly pregnant women, newborns, the elderly, and adults with impaired immune systems. Healthy adults and children sometimes are infected with L. monocytogenes, but they rarely become seriously ill. Babies can be born with listeriosis if their mothers eat contaminated food during pregnancy.
Although my boys are healthy teens, I was still concerned about the Gala apples in their lunch boxes today. I called Wegmans where I bought the apples and asked if they used Bidart Bros as a supplier. I was assured that Wegmans does not buy from that supplier. If I had been told they did, I’d have been running new lunches up to my boys’ schools today in case the apples were contaminated and had came in contact with other items in their lunches.
