Quick Answer
At high altitudes, pressure canning venison requires adjustments to processing times and pressure levels to ensure proper sterilization and prevent spoilage. Failure to do so may lead to undercooked or unsterilized meat, which can cause foodborne illness. This is especially critical when canning low-acid foods like venison.
Understanding Altitude Adjustments for Canning Venison
When canning venison at high altitudes, it’s essential to understand the adjustments needed for processing times and pressure levels. For every 1,000 feet of altitude, the boiling point of water decreases by approximately 1.8°F. This affects the pressure canner’s ability to reach the required temperature for sterilization. Using a pressure canner with a dial gauge is crucial for accurate pressure readings.
Safe Processing Times and Jar Sizes
To ensure safe and proper canning of venison, use a pressure canner with a dial gauge and follow tested recipes. The USDA recommends the following processing times for venison steaks (1-inch thick): 30 minutes at 10 pounds pressure (up to 1,000 ft), 35 minutes at 12 pounds pressure (1,001-2,000 ft), and 40 minutes at 15 pounds pressure (2,001-3,000 ft). When canning ground venison, use a 10-minute processing time for steamer basket loads and 15 minutes for loads packed in jars. Use 1-quart or 1-pint jars for ground venison and 1-quart jars for steaks.
Shelf Life and Storage Guidelines
After proper canning and processing, the shelf life of canned venison can range from 12 to 24 months, depending on storage conditions. Store sealed jars in a cool, dark place, away from direct sunlight and moisture. Check the seals regularly, and use a food canner’s testing gauge to ensure the seal is tight and the lid is concave.
