Low-acid foods require special care

Low-acid foods require special care is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.

Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.

When in doubt discard

When in doubt discard is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.

Safety sources to keep handy

For preservation methods where process details affect safety, use current research-tested guidance rather than improvising.
