WalMart sells Keystone canned meats.
Here are the codes explained by Joanie from Keystone:
Shelf Life and Production Code The USDA recommends a shelf life of 5 years for optimal taste, provided the integrity of the can is not compromised in any way. Once opened, the meat should be treated the same as any other fresh meat. The USDA does not require a use by date on the can due to the extended shelf life. The numbers you need are on the bottom of each can. 15826 is our USDA establishment number and the other set of numbers is the date of production. For instance, if your production code was B9174, it would be: B = beef 9 = 2009 (the first number after the letter is the last number of the production year) (0 = 2010, 1 = 2011) 174 = the 174th day of the year according to the Julian calendar. These 3 numbers are always the day of the year. All of our Keystone Heat and Serve canned meats can be read in this manner. The broths are the same as the meats.
C) We have had a side of beef (from a local farm) processed at Manley's and we have been a regular customer of Grabill Country Meats for couple yrs. Both are good local Indiana companies. BUY INDIANA.
I try to buy Indiana whenever I can, but Werling cans BACON. BACON trumps state loyalties.
