Pacific Organic Produce, San Francisco, is recalling mangoes that were contaminated with Listeria monocytogenes.

The Tommy Atkins mangos (PLU numbers 94051 94959)were sold under the Purity Organic brand between the dates of April 14 and May 2, a U.S. Food and Drug Administration (FDA) news release reported.

No illnesses have been reported so far and other products and mangoes from the company are believed to be safe to eat.

The recall was issued as a precautionary measure after an FDA sample came back positive for Listeria monocytogenes.

Symptoms of the infection include: "fever, muscle aches and gastrointestinal symptoms such as nausea or diarrhea," the news release reported.  The illness is especially dangerous to pregnant women and those with weakened immune systems; healthy adults and children usually are not affected by the bacteria.

The PLU number is printed on a sticker that can be found on the fruit. The mangoes were shipped to retailers in five states: "Arizona, California, Colorado, New Jersey and Texas" the news release reported.

Consumers who have products stamped with this code that was purchased between April 14 and May 2 should discard the fruit. Consumers are also urged to keep the receipt received at the time of purchase or the PLU sticker.

Retailers or consumers that have questions about the recall can reach out to Amy Rosenoff at Pacific Organic Produce customer service at 415-673-5555, the office is open from 8:00 a.m. and 4:00 p.m. PT Monday through Friday.

In order to avoid Listeria contamination consumers should rinse all produce thoroughly and scrub firm produce such as melons. Keeping uncooked meat and poultry separate can also reduce the change of Listeria contamination, the Centers for Disease Control and Prevention (CDC) reported.

Consumers are also urged to keep their kitchen areas clean and thoroughly wash all cutlery and cutting boards.
