The FDA is warning consumers about specific cheese products made by the New York-based Peregrina Cheese Corporation. A bacteria called Listeria monocytogenes was detected during routine testing of their products - this bacteria has the ability to cause miscarriages in pregnant women and fatal illnesses in the very young and the elderly. No illness has been linked to these products so far, but the FDA is advising that these products be avoided.

The affected products are:

• Queso Fresco Fresh Cheese Mexican style soft cheese: 14-ounce foil wrapped packages marked with lot number 4469 or 4477 affixed to each package on a white sticker, UPC number 8 17424 00024 6,  Plant # 36-8431.
