Frugal Kitchens 101- Opening Jars and Cans

Just a quick show of hands, how many of you routinely wash the lids of every jar and can you open prior to opening?  If you don't this Frugal Kitchens 101 post may just change your mind.  Before jars and cans get to your grocery store they are stored in large warehouses where there more than likely will be rodents and other pests like roaches.  True they can't get into the cans or jars but they can still leave their mark.  If you home can you still cannot be 100% sure they have not come into contact during storage with rodents or other pests especially if your home canned foods are stored in a location that may come into contact with any little critters.  Rodent contamination can be a huge problem even if you don't see them as can other critter contamination.  My rule of thumb is to wipe down any tin cans  and the lids of home canned foods I open with a dish cloth spritzed with a 50% ethanol (rubbing alcohol)  solution.  Alcohol is the ideal sanitize for any biologicals assuring no organisms that will contaminate the foods opened.  Always, always, always wash or sanitize the lids of cans and home canned foods prior to opening them.
