Safety
Canning, freezing and drying have long been used as safe methods for
food preservation. Using correct techniques ensures the quality and
safety of the food. Approximately 10 years ago, the United States Department
of Agriculture (USDA) revised the processing times for home-canned foods
using altitude as one of the factors. Those processing times have changed
somewhat from earlier recommendations. To ensure safety, use only sources
of information published after 1988. Below are recommended times for
areas of the country with an altitude of 1,000 feet or below.
