Is it safe to pressure can meat that has been previously frozen?

Understanding the Guidelines

Pressure canning is a safe way to preserve meat, including previously frozen meat, as long as it’s done correctly. The USDA’s Complete Guide to Home Canning recommends pressure canning as the preferred method for canning frozen or refrigerated meat. This is because pressure canning can reach the high temperatures needed to kill bacteria and other pathogens that may be present in the meat.

Temperature Control and Freezing

When pressure canning previously frozen meat, it’s essential to ensure that the meat has been thawed and heated to a safe temperature before canning. The USDA recommends heating the meat to an internal temperature of at least 165°F (74°C) before canning to ensure that any bacteria are killed. It’s also crucial to follow the recommended pressure canning guidelines for time and temperature to ensure that the meat is heated to a safe temperature throughout the canning process.

Best Practices for Canning Frozen Meat

To can frozen meat safely, it’s recommended to follow these best practices: thaw frozen meat in the refrigerator or in cold water, not at room temperature; heat the meat to an internal temperature of at least 165°F (74°C) before canning; use a pressure canner that’s in good working condition and follow the recommended guidelines for time and temperature; and always follow safe canning practices, such as sterilizing equipment and jars, and leaving headspace in jars as recommended.
