"We are aware of no illnesses related to the consumption of these products," Wawona President Brent Smittcamp said in a statement. "By taking the precautionary step of recalling product, we will minimize even the slightest risk to public health, and that is our priority."

Smittcamp is urging customers not to eat any of these stone fruits -- meaning fruits with large pits -- and to either destroy them or return them to a nearby store for a refund.

Whole Foods is also recalling several of their " made-in-store items such as cakes, tarts, salsas, and prepared salads" that may contain the contaminated fruit.

In addition, Wegmans has recalled several of its baked goods that contain fruit from Wawona Packing Co. This includes cakes, pies, tarts and other pastries. For a full list, see FDA.gov

Listeria monocytogenes is a bacterium that can cause listeriosis. The most common symptoms of listeriosis are gastrointestinal issues (such as diarrhea), fever and muscle aches. Pregnant women, infants, older adults and people with weakened immune systems are particularly at risk for a more serious infection, according to the Centers for Disease Control and Prevention

If you have already eaten one of the recalled products and begin to feel ill, see your doctor and tell him or her about the recall.

"Your doctor will make a diagnosis and should report any positive test findings for Listeria monocytogenes to public health authorities, who will then report it to the Centers for Disease Control and Prevention," Wawona states in an FAQ about the recall.
