Adjustments are critical for food safety at higher elevations!

The processing time (for water bath canning), pressure requirement (for pressure canning) and blanching time (for freezing and drying some foods) all need to be increased at higher elevations to destroy heat-resistant bacteria and to ensure home-preserved food products are safe to enjoy.

Important Steps for Safely Preserving Foods at High Elevation

1. Determine your elevation using a resource such as whatismyelevation.com (Enter your address, city, and state in the 'Enter your location' box.)

2. Use tested recipes and follow all high elevation adjustment instructions provided (sometimes referred to as high altitude adjustments)--including processing time, required equipment, pressure, and/or blanching time.
