The method used for canning a product is determined primarily by the acidity of the food or mixture of foods being canned. Low-acid foods (those with a pH level of 4.5 or higher) must be processed in a pressure canner to be free of botulism risks. All fresh vegetables except for most tomatoes are low acid foods. Other low-acid foods are red meats, seafood, poultry and milk.
