Avoid Contamination: Where to go for safe canning recipes


Author: Melanie Jewkes

If I gave you a delicious-looking hamburger, complete with all your favorite condiments, and told you I couldn’t guarantee it had been cooked long enough, would you eat it?

Safe Resources for Canning

I’m guessing you would probably pass and choose not to eat it. Why? Because eating raw meat posses a risk. We know from scientific studies that raw ground hamburger can contain bacteria called E. coli, which can make anyone sick and can be life threatening for young children and older adults. Does this mean we shouldn’t eat ground hamburger? No, because scientific studies have also shown that if ground meat is cooked until a meat thermometer shows 160 F, then bacteria is killed, providing a safe food product. There is no need to avoid eating ground hamburger—the real answer to concerns about the safety of cooked meat is following the USDA scientific guidelines

So it is with canning. The process of preparing food and sealing it in jars for a long shelf life is a scientific process. Rigorous and thorough studies in USDA-endorsed laboratories have already determined what is needed to protect your home-bottled goods from going bad and from becoming contaminated. When these scientific processes are not followed accurately, the canned goods pose a risk similar to that of undercooked meat. Canned goods not processed accurately could have a poor quality, could spoil quickly or could contain a toxin that is taste-less, odor-less, and cannot been seen with the naked human eye. This toxin grows from a germ called Clostridium botulinum, which causes the potentially deadly illness botulism. Botulism is rare, but scientific studies have proven proper processing procedures, including time and temperature, to kill the germ before it grows to a toxin.

What’s the secret to safe home-bottled goods? Follow safe scientific canning guidelines.

Be aware that a simple Internet or pinterest search for a canning recipe is NOT the safest way to find a recipe to preserve your food. Be sure to only use recipes and procedures that are scientifically studied and USDA approved.
Canning is not cooking—it is a scientific process that must be followed accurately to ensure safety.
