LOS ANGELES , November 17, 2011 () – Food safety officials have found an unlikely ally in their attempts to locate the source of food-borne illness outbreaks: grocery store loyalty cards, USA Today reported on Nov. 17.

According to the article, victims of food-borne illness outbreaks are not required to release their loyalty card records to food safety officials, and some grocery stores will refuse to release the records even with written consent from the customer.
