Notice the wording with this, it’s not “This is not healthy to eat after this date” but more “This won’t taste as good after this date”, and the date is more than 3 years after I bought the product, a well known canned meat product.
The holes were added by me to get the product out of the can in a single piece after several minutes of shaking and tapping the can on the plate failed to dislodge my dinner for cooking. So I found something with a sharp point to add a vent to keep a vacuum from forming behind the meat product and allow air to get back there to equalize pressure on both sides so I could heat my dinner.
And then I ate it and chugged a liter of Cherry Coke. The End.
