I'm having a very simular problem, however mine is that, we went to walmart last night Friday, September 26th and purchased some chicken. I went to put the chicken in the slow cooker and opened the package and almost vomited the smell was so bad.
I then go and look at the package and it says sell by September 24th. Even just being two days after I purchased it and the next morning opening it. I called them and they had no concern really. "Bring it in and we'll replace it" never again shopping at walmart.
I moved to texas from wisconsin, and back home I always purchased meat from a butcher shop. Time to find one in Texas!
Reason of review: Selling meat past date.
Monetary Loss: $500.
Preferred solution: Refund, cost of cleaning supples that had to be tossed away from contamination .
