FNH-00268 View this publication in PDF form to print or download.
When some foods are not packed or stored correctly, botulinum bacteria grow to make
a poison.
IT CAN KILL PEOPLE WHO EAT IT!
Botulism can be in these foods when they are poorly stored.
BOTULISM WILL GROW:
- in low-acid foods (meat, fish, vegetables).
- where no air is present.
- where temperature is warm (over 38°F).
- in foods stored for some time.
SYMPTOMS OF BOTULISM
- Double Vision
- Dry Mouth
- Dizziness
- Vomiting
- Poor Balance
Botulism has no taste or smell!
Botulism cannot be seen!
DO NOT TASTE BEFORE BOILING!
Boil 15 minutes any food that may have been stored improperly. Boiling destroys the botulinum poison.
TO STOP BOTULISM GROWTH
Store food in these ways.
- Refrigerate
- Freeze
Pressure can at 11 pounds pressure if your canner has a dial gauge like this one.
10 pounds pressure if your canner has a weighted gauge.
Dry for cache storage wrapped in cloth or paper—NOT PLASTIC.
Ferment fish and meats in the traditional way.
Keep foods cold while they ferment (below 38° F).
Only use plastic bags for freezer storage and temporary refrigerator storage.
Do not use plastic to ferment meats and fish. Let a little air get to the fermented
foods.
BOTULISM IS PREVENTABLE
- Store meats and fish carefully.
- Boil auspected foods before tasting.
WHEN IN DOUBT—THROW IT OUT!
