For those who come after, boiling previously canned for 5-10 minutes is recommended because any toxins will be destroyed. Spores of the problematic bacteria could remain, so it is necessary to consume the food immediately and to not feed it to individuals with compromised immune systems, particularly infants under 12 months.

I believe the above is correct based on my own personal reading of available information. I do not have formal training in food safety or science. Please do your own research, and none of what I've said applies to food that will be canned. Also, please correct me if I am wrong.
