I remember hearing that you shouldn’t use dented cans when I was younger. I don’t recall hearing why, but have pretty much avoided buying them. I received a box that included some cans this week. Unfortunately, a couple of those cans had gotten damaged in shipment and arrived dented. I don’t mean small dents, like the ones that happen when you accidentally drop a can while putting groceries away. I mean big dents. I decided to try and do some research on dented cans.
According to the USDA, if you’ve stored cans in a cool, dry place they can safely be stored from anywhere from 18 months (fruit) all the way up to 2 to 5 years (meat and vegetables). that’s actually good information to keep in mind when planning emergency food storage as part of emergency preparedness. The article continued to explain that canned goods tainted with botulism often show signs including leaking, bulging and bad dents. Another article that I found on the Penn State site further explained that dents in cans put stress on the seal, causing the can to leak and allowing germs to get into the can.
Another type of survival food is freeze dried food. I don’t know much on the subject except for the basic principe, that if you remove the moisture from a food and seal it so moisture can’t get back in then the food can be stored for years without refrigeration and danger of spoilage.
I do not generally have an emergency food supply. If a severe storm is coming I’ll stock on whatever we’ll need to get through it. Do you have an emergency food supply?
