Can you use a 7 year old jar of mince meat for pie?

It is not advisable to consume canned goods that are more than 12-18 months past their suggested expiration date. Home-canned foods should not be consumed more than 1 year after they have been canned. Botulism, a deadly foodborne illness, can occur in rare cases when canned foods are improperly processed or stored. Signs of botulism include vomiting, diarrhea, fatigue, blurred vision, and muscle weakness. If you suspect that a can of food may be contaminated with botulism, do not eat it and contact your local health department.
