48 hours. Mel how are you feeling.
I work in the can manufacturing industry, I'd recommend not eating food from cans that bulge, the foil tops or lids, weeping from seams, exploding cans, anything irregular in a can. Cans that are gassing hydrogen and making the cans appear to not have a tight vacuum seal--are decomposing, rotting or the food is chemically reacting with parts of the can or coatings inside the can.
If you contact the manufacturer, you'll need the printed codes from both the label, printed on the paper outside layer or on the printed can itself, as well as the codes printed on the ends of the can or under the label if it is paper. One set of codes is from the food manufacturer putting the food in the can, the other set is from the can manufacturer.
Let us know you are okay Mel. Thanks, Bliss
