It's positive reinforcement to have confirmation that money spent on quality food isn't wasted.
A story at CNN.com tells about the recall of 380,000 pounds of deli meat sold exclusively by Wal-Mart which has been found in an isolated occurrence to be contaminated by Listeria monocytogenes.
According to the description at Wikipedia "It is one of the most virulent foodborne pathogens with 20 to 30 percent of clinical infections resulting in death. Responsible for approximately 2,500 illnesses and 500 deaths in the United States (U.S.) annually, Listeriosis is the leading cause of death among foodborne bacterial pathogens with fatality rates exceeding even Salmonella and Clostridium botulinum. "
So far the only confirmed cases have been related to deli meats used in ready to eat sandwiches with the brand name, Grab and Go. In my experience, anything with a name like that is best dealt with by averting one's eyes and quickening one's pace toward other areas where real food can be found.
According to the article, "The meats were produced on dates ranging from June 18 to July 2, 2010. The "Use By" dates range from August 20 to September 10, 2010". So, at the least, the little critters have only had about seven weeks to strengthen their numbers. And how about that two month shelf "life".
