Wysong Dog Food Recall

Wysong, a Midland, Michigan holistic pet food manufacturer, has issued a voluntary recall of its dry dog food. The affected batches were manufactured in June, July, and August of 2009. This recall is due mold spores discovered in specific batches of Wysong brand dry kibble. The Wysong web site states that these mold spores were related in part to the high heat and humidity experienced during the summer months combined with a malfunctioning moisture sensor used in the manufacturing process.

Wysong has tested other batches of their food for mycotoxins and the results were negative. The most common problem associated with the consumption of moldy foods is diarrhea. According to Dr. Greg Aldrich of the Petfood & Ingredient Technology, Inc., “The only purpose behind drying [the kibble] is to decrease the water activity to a point that it limits microbial growth … unfortunately, achieving just the right level of heat and dryness while not overcooking or damaging the food is tricky … if we have a product “case hardening” that prevents moisture escape from the interior of the food piece, the water activity may be high enough for mold to occur.
