Quick Answers
I have some green beans that were canned 5 years ago; are they still alright to eat?
The recommended storage period for canned food is one
year. However, most foods will be safe to eat for more
than 1 year if the seal is still good. Major changes
that would occur during a long storage period will be in
quality--color, flavor, texture and nutrient retention.
Of course, those changes will be more extreme as storage
time increases. If you want to eat the beans that have
been stored for 5 years, take precautions! Check the
seals first. If they are still intact and there are no
indications of spoilage, be sure to boil the beans for
10 minutes before eating if you live below 1,000 feet,
and 11 minutes if you live above 1,000 feet.
