Check your apples. (No, put your phone down, not those Apples)

North Bay Produce is voluntarily recalling several varieties of apples due to possible listeria contamination.

The affected fruit was shipped between Oct. 16-21 from North Bay to retailers in Florida as well as Illinois, Kentucky, Louisiana, Michigan, North Carolina, Texas and Wisconsin.

The varieties in question include McIntosh, Honeycrisp, Jonathan, Fuji, Jonamac and Red Delicious apples. Recalled apples were sold in plastic bags under the brands Great Lakes and North Bay Produce Pure Michigan as well as unbranded in clear plastic tote bags, white paper tote bags, and individually in retailers display trays.

The apples should be discarded or returned. No illnesses have yet been linked to the recall. Symptoms from listeria can show up the day of exposure up to a month later. The symptoms are mild flu-like: headaches, muscle aches, fever, nausea, and vomiting. If the infection spreads to the nervous system it can cause a stiff neck, disorientation, or convulsions.
