A national survey conducted by the USDA-NIFA National Center for Home Food Preservation in 2000 found that many people use canning practices that put them at high risk for foodborne illness. Over the years, changes in scientific expertise, as well as canning equipment, have occurred, so there is new information on the right type of methods, canners, jars, and seals. For instance, there are two types of canners for home canning: the boiling water-bath canner, and the pressure canner. Using the pressure canner for low-acid foods such as vegetables, meats, poultry, and fish is a must to prevent botulism. The water-bath canner is used for high-acid foods such as fruits, jams, and jellies.
