Water-bath canning techniques may no longer be safe.
For years, we canned tomatoes and homemade tomato sauce the way grandma taught us: using the water bath method. This involved packing sterilized jars with hot (cooked) fruit or tomatoes and boiling for a designated amount of time, usually an hour or more for tomatoes. That’s not true anymore. In this age of increasing food contamination, you don’t want anything bad to come out of your kitchen. What could happen? Listen to what Renee R. Boyer, Assistant Professor, Food Science and Technology, Virginia Tech; Julie McKinney, Project Associate, Food Science and Technology, Virginia Tech…
… high-acid foods prevent the growth of spores of the bacterium Clostridium botulinum, which can’t be killed by boiling. Foods with a pH more than 4.6 allow the spores to grow. If spores of C. botulinum are allowed to grow, toxin will form, and consumption of C. botulinum toxin is deadly. Symptoms from the consumption of this toxin develop within six hours to 10 days and include double and blurred vision, drooping eyelids, slurred speech, difficulty swallowing, and muscle weakness. Paralysis of breathing muscles can cause a person to stop breathing and die unless mechanical ventilation is provided.
Didn’t mean to scare you. But this is serious business. Take precautions. (more…)
