12 Foods that can cause deadly botulism (2024)

FAQs

What foods are most likely to cause botulism? ›

The typical source of foodborne botulism is homemade food that is improperly canned or preserved. These foods are typically fruits, vegetables, and fish. Other foods, such as spicy peppers (chiles), foil-wrapped baked potatoes and oil infused with garlic, may also be sources of botulism.

The botulinum toxin has been found in a variety of foods, including low-acid preserved vegetables, such as green beans, spinach, mushrooms, and beets; fish, including canned tuna, fermented, salted and smoked fish; and meat products, such as ham and sausage.

Symptoms generally occur between 12 and 36 hours after eating the contaminated food. Most human cases of botulism are caused by improperly cooked, preserved or canned foods where growth of the bacterium has produced the toxins.

Commercial or home-canned food products with bulging lids or a bad odor should not be eaten. However, botulism has also been associated with foods that smell and taste normal; therefore, the smell and taste of food should not be used to determine if it is contaminated. Never taste food to determine its safety.

Fats / Dairy

Also any recipe that use one or more of these ingredients, such as mayonnaise, caramel, pudding, cream soups, cream vegetables, refried beans, nut butter (all kinds), pesto, chocolate (all kinds) etc. WHY: These will go rancid if not refrigerated, developing harmful bacteria.

Intestinal (infant and adult) botulism is typically associated with the ingestion of spores that germinate and produce toxin in-vivo that may be present in items such as foods, soil, dust, unpasteurized honey and peanut butter.

By cooking under pressure, you can increase the temperature of boiling water from 100°C (212°F) up to 116°C (240°F). This is the minimum temperature necessary to destroy botulism spores, and the only way to guarantee safe canning for food items such as vegetables, meats and seafood.

High-acid foods such as jams, jellies, fruits, pickles, relishes, salsas, and tomatoes with added acid (i.e., one teaspoon of vinegar), only need the “boiling water bath” method of canning because the acid prevents botulism bacteria from growing.

Foodborne botulism can happen by eating foods that have been contaminated with botulinum toxin. Common sources of foodborne botulism are homemade foods that have been improperly canned, preserved, or fermented. Though uncommon, store-bought foods also can be contaminated with botulinum toxin.

You cannot see, smell, or taste botulinum toxin – but taking even a small taste of food containing this toxin can be deadly. Click on the following tips for details on how to protect yourself and the people you feed. When it doubt, throw it out!

What canned foods can have botulism? ›

Since the canning process forces air out of food, the C. botulinum bacteria may find incorrectly or minimally processed canned foods a good place to grow and produce the toxin. Low-acid vegetables such as green beans, corn, beets, and peas, which may have picked up C. botulinum spores from the soil, are at risk.

Botulism is a rare but serious illness caused by a toxin that attacks the body's nerves. Symptoms of botulism usually start with weakness of the muscles that control the eyes, face, mouth, and throat. This weakness may spread to the neck, arms, torso, and legs.

Botulism can be fatal if left untreated. But most people who receive a prompt diagnosis and treatment can make a full recovery from the illness. They return to normal functioning throughout their lives. Botulism is a serious illness that attacks your body's nervous system, causing weakness and muscle paralysis.

Types of botulism include foodborne, infant and wound botulism. Botulism is usually caused by a bacteria called Clostridium botulinum. Symptoms include muscle weakness and paralysis. Treatment typically includes antitoxin to prevent the toxin from causing more damage.

The most common form of botulism in the United States, infant botulism, is caused when ingested C. botulinum spores colonize and subsequently produce toxin in the intestines of affected infants.

Honey is the one identified and avoidable food reservoir of C. botulinum, the bacterial spore that causes infant botulism. While most cases of infant botulism today are not caused by exposure to honey prior to illness, it is the only avoidable source of exposure to the bacteria.

Only cooking or boiling food destroys botulinum toxin. Freezing does not destroy the toxin. If you prepare or eat traditionally prepared Alaska Native foods, the food safety tips below may decrease your risk of botulism. 1.
