The Meat and Poultry Hotline does provide general information regarding safe methods of food preparation. However, we do not provide in-depth, step-by-step instruction on home canning. This has traditionally been the role of USDA's Cooperative State Research, Education, and Extension Service (CSREES-USDA).
The National Center for Home Food Preservation is your best source for current research-based recommendations for most methods of home food preservation. The Center was established with funding from CSREES-USDA to address food safety concerns for those who practice and teach home food preservation and processing methods. This site offers the USDA Complete Guide To Home Canning, factsheets, consumer bulletins, technical bulletins, and literature reviews on home food preservation.
The Meat and Poultry Hotline strongly advises that home canners use only up-to-date, scientifically tested methods such as those found in the USDA Complete Guide To Home Canning. Improper canning presents a serious risk of foodborne illness from Clostridium botulinum.
