Unfortunately, I did a little research online and saw that JBS Swift is one of the four major suppliers of beef to Costco. I just loaded up a couple of weeks ago and seriously considering taking it all back.
Given that the beef in question was packaged on April 21, it’s highly unlikely that any of it was in the batch you bought at Costco. That said, they’ll take anything back. I got some very tough NY strips one time and they cheerfully refunded my money without the need to actually bring the steaks back. Just take your receipt.
That’s a good point. I think I’m probably safe with my latest purchase, but should probably run through the freezer and check the dates on the Foodsaver bags.
