Bests & Worsts Reviews from Amazon

I ordered a case of the chicken and the beef back in January of 2014. The taste and quality of the meat was good and I thought I finally found a healthy alternative to the heavily processed, chemically filled storable foods that most other suppliers offer. But Its now been a little over one year and I noticed 4 of the cans of beef are actually bulging, which means gas is forming inside the can. The meat is not safe to eat when cans start bulging! At least none of the cans of chicken are bulging yet, but I'm now worried about the long term value of any of these cans and have lost trust in the brand. Is it only a matter of time before the rest of the cans go bad? I'll also note that these cans were stored in ideal conditions, climate controlled, low humidity. I do not feel safe buying any more of these for long term use. I'll use up the cans I have left and have to look elsewhere. For reference, the lot numbers on the bad cans are: B3312 15826
