12 Foods that can cause deadly botulism (2022)

UPDATE 15 Feb 2022: Several years ago, when I wrote this piece, it was to share what I had learned about botulism after making a potentially deadly mistake. Since then, numerous readers (Thank you!) have asked questions about various foods in their kitchens. I am NO expert. I do not have all the answers. Please, if you have a question about botulism, follow the links in this article and contact your local poison center or county extension agent. And always, follow the old maxim: If in doubt, throw it out.

A couple of weeks ago, I dropped a sprig of fresh, aromatic organic rosemary in a pretty bottle and filled it with olive oil. What I didn’t know then is that I might have killed us with that oil.

It turns out, herb-infused oil is one of the twelve foods, or more precisely, food groups, that can cause botulism, a rare, but life-threatening food-borne illness that causes paralysis and may take weeks, even months to recover.

If you read me regularly, you’ll know I included an herbed oil in a post, 5 Ways to use fresh rosemary. A few hours after I published that post, an alert blogger friend notified me of the danger. I retracted the tip immediately.

To reach as many people as possible, I also published–and publicized as best I know how–a new article, clearly warning of the risk, along with a link to the University of Maine Cooperative Extension office article, Safe Homemade Flavored and Infused Oils.

How did this happen?

How could I, a grandmother who has known about botulism since my teens, not know that fresh herbs carry the bacteria, Clostridium botulinum, which causes botulism, or that putting them in oil would provide exactly the environment the bacteria needs to grow?

Fresh rosemary

It never occurred to me such a thing could be harmful. In how many gourmet gift shops have I seen such bottles filled with oil and herbs? Turns out, commercial purveyors add a special acid-rich ingredient to their herbed oils, in a process not easily duplicated at home.

But also, the Center for Disease Control and Prevention (CDC), in “Botulism prevention: Many cases of botulism are preventable“, tells us that new sources of botulism poisoning are found nearly every decade. Given I’m more than five decades away from my last Home Ec class, where we learned about what causes botulism, I may have some catching up to do.

What else might I have missed in the last 50-some years?

My experience set me to wondering. What other foods carrying the bacteria escaped my ken? How we can protect ourselves when cleaning, preparing, eating and storing those foods? I did some digging.

In my research, I found twelve foods and/or food groups that can put us and our families at risk for botulism. Most I already knew about. But baked potatoes wrapped in foil? That one’s new too. Thankfully, we’ve never baked our potatoes in foil.

Is this a comprehensive list? Don’t count on it. I’ve done my best to ferret out the foods that may put us at risk. The twelve foods in the joint lists you’ll find on this page come from no less authoritative sites than the websites of the CDC and the United States Food and Drug Administration (FDA).

Before I share the lists, you may be wondering what botulism is and what causes it. Here are the facts as I understand them.

Note: I have found that government web pages seem to be moving targets. I check this page periodically, but if you find a broken link, I would appreciate it if you would mention it in the comments below so I can track down the new location.

What is botulism?

Botulism is a deadly food-borne disease caused by the bacterium C. botulinum. This rod-like bacteria lives in the soil and can be found in many plants and animals.

When active, it produces a neurotoxin that attacks the nerves in our muscles, including the ones that help us breathe.

Only a small amount–we’re talking nano grams–can immobilize and kill a person. Because the symptoms are similar to other diseases, such asGuillain-Barré Syndrome, doctors find it difficult to detect. Diagnosis takes a week or more.

Thankfully, an anti-toxin is available to help treat the illness, and in most cases, prevent death. Recovery, however, may take weeks or months.

Other ways we can get botulism

While this article concerns itself with food-borne botulism, you should know that it can invade our bodies through other means, such as wounds and, possibly, according to the FDA, (pdf, p. 109), through invasive digestive-track surgeries.

In addition to these, MedScape, which lists six forms of botulism, includes inhalational botulism and adult intestinal colonization botulism.

Infants can get it from eating dirt, as well as from certain foods that are not dangers to children over one year old or to adults. Those foods are on the list, in their own section.

Fortunately for humans, C. botulinum needs a near-oxygen-free environment to grow, and doesn’t like acid. Air and acids such as vinegar, lemon and lime juice help to keep us safe from food-borne botulism.

That’s one reason people preserve foods by pickling them in vinegar.

Three botulism facts to keep in mind

While it is deadly, C. botulinum needs a specific environment to grow. We can lessen our chances of getting this disease if we remember these three facts.

12 Foods that can cause deadly botulism (4)

  1. C. botulinum may be carried on almost any food that has little or no acid. Green beans, Brussels sprouts, carrots and cabbage, like most vegetables and many fruits, contain very little acid. Other examples (not a complete list) of low-acid foods include mushrooms, meats, fish and eggs. C. botulinum spores may piggy-back on any such foods.
  2. C. botulinum needs a low-oxygen, low-acid environment.When we place low-acid or non-acidic foods in a low-oxygen environment, such as a home-canning jar, we give them the perfect environment to go forth and multiply. Similarly, covering low-acid foods in oil reduces or eliminates oxygen availability and provides a botulinum-loving environment. That’s why my herbed oil could have become a deadly, if tasty, food.
  3. C. botulinum outbreaks in the U.S. occur most often due to improper home-canning. If you plan to can food at home, or to eat home-canned food, follow the guidelines outlined in the CDC’s article titled Home Canned Foods: Protect yourself from botulism.

Now, on to that food list. There are two, actually–one for infants, and another for everyone else.

Which foods most likely carry botulism?

Reports from the FDA, as well as the CDC, name twelve foods, or food groups that may carry C. Botulinum to humans. They break it up into three foods for infants under one year, and nine that may pose a risk to all the rest of us.

While I don’t find this statement in the second edition, in the first edition of its Bad Bug Book, the FDA said,

Most of the 10 to 30 [botulism] outbreaks that are reported annually in the United States are associated with inadequately processed, home-canned foods, but occasionally commercially produced foods have been involved in outbreaks. [Emphasis mine.] Sausages, meat products, canned vegetables and seafood products have been the most frequent vehicles for human botulism.

On its FoodSafety.gov website, the United States Department of Health and Human Services (DHHS), under which both the CDC and FDA run, identifies the first eleven of these twelve at-risk foods this way. I ran across the twelfth group on a separate FDA page.

Infants

12 Foods that can cause deadly botulism (6)

Infants one year of age and under must never eat the following foods.

  1. Honey
  2. Home-canned vegetables and fruits
  3. Corn syrup

Note that infant botulism is classified separately, not as a food-borne illness. The Minnesota Department of Health explains it this way: An infant can get botulism

When a baby eats or drinks something that contains spores of the bacteria – the hard-shelled form that the bacteria take on when they aren’t able to grow and reproduce.

Because honey, home-canned vegetables and fruits, and corn syrup may contain the spores, even if they’re not actively reproducing, these foods, as well as soil and even dirt in the carpet, may cause infant botulism.

Sometimes you have to wonder how we ever managed to over-populate Mother Earth, don’t you? Not that we should look at these dangers flippantly. Not at all! But to remind ourselves, lest we think we have to put our babies in bubble suits, that this disease is relatively rare.

Children and adults

For children one year and older, and for adults, the DHHS identifies the following high-risk foods.

  1. Home-canned foods with a low acid content
  2. Improperly canned commercial foods
  3. Home-canned or fermented fish
  4. Herb-infused oils
  5. Baked potatoes in aluminum foil
  6. Cheese sauce
  7. Bottled garlic
  8. Foods held warm for extended periods of time
  9. Frozen, fully cooked products (Not on the DHHS list, but found in a separate article published by the FDA).*

*The FDA , in its article titled Frozen, Fully-Cooked Products & Botulism – Food Safety Advisory, explains why they’ve issued this caution and what we need to do to protect ourselves.

How do we protect ourselves?

The DHHS offers this somewhat cryptic prevention advice.

  • Be very careful when canning foods at home
  • Do not let babies eat honey
  • Get prompt medical care for infected wounds

The CDC gives a longer version with plenty of specific information to help you protect your family. Please go to the their web site and read everything they’ve published about botulism. We don’t want to take any more risks than we have to!

You can also find information on safe home canning methods through your local county extension office. Some offer classes. They may also offer free, easy-to-follow, how-to printed instruction guides. You can find them through this interactive map on the Gardening KnowHow site. Sure, it’s a gardening site. The extension offices help gardeners as well as home food preservationists.

What to do if you think you may have botulism-infected food

12 Foods that can cause deadly botulism (8)

Wear plastic gloves when handling suspect food

About half a century ago, in an ancient Home Ec class, I learned that the first rule of thumb in food safety is always, When in doubt, throw it out. According to the CDC, that’s still sound advice, but with this bug, it’s more complicated than that. We can’t just chuck it down the drain or into the dumpster. C. Botulinum is a bio toxin. Handle suspect foods with plastic gloves and a lot of care.

How to tell when to doubt? Check out the CDC guide for that. Please read the complete guide, especially this section: Safely dispose of food and cans that may be contaminated.

Stay safe–Do some research

That’s what I’ve learned about botulism so far. Thankfully, botulism poisoning is rare. I’ll return and post updates as I learn more.I hope the links on this page help you to make healthy decisions about preserving the foods you love and help to keep you and your loved ones safe

Please don’t assume I’ve covered every food and every possibility. Follow the links. Do the research. Ask questions of the folks at your local county extension office. (To find yours, see link in item #2 under “Breaking it Down.”)

If you have a question about a specific food and don’t find it in any of the links referred to on this page, write, call or send an e-mail to the Centers for Disease Control. Here is the contact information they provide on the page I linked to earlier in the article.

What causes death in botulism? ›

organisms. Botulism (“BOT-choo-liz-um”) is a rare but serious illness caused by a toxin that attacks the body's nerves and causes difficulty breathing, muscle paralysis, and even death. This toxin is made by Clostridium botulinum and sometimes Clostridium butyricum and Clostridium baratii bacteria.

What foods contain 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.

Can peanut butter have botulism? ›

It was accepted by the parties that the peanut butter was not actually contaminated with botulism, but rather contained inactive botulism spores. Such spores exist commonly throughout nature, and often appear in food. Under ordinary circumstances, the spores are digested without incident.

Can botulism grow in vinegar? ›

Because vinegar is high in acid, it does not support the growth of Clostridium botulinum bacteria. However, some vinegars may support the growth of Escherichia coli bacteria.

Where is botulism most common? ›

While home-canned food is the most common source for botulism, commercially prepared foods have been implicated as well. Vegetables, fish, and condiments are the most commonly implicated foods; however, beef, dairy products, pork, poultry, and other foods have also been implicated.

What are 4 symptoms of botulism? ›

Signs and symptoms might include:
  • Difficulty swallowing.
  • Muscle weakness.
  • Double vision.
  • Drooping eyelids.
  • Blurry vision.
  • Slurred speech.
  • Difficulty breathing.
  • Difficulty moving the eyes.

What two organ systems are affected by botulism? ›

Botulism caught from food usually affects the stomach and intestines, causing nausea, vomiting, constipation, diarrhoea and abdominal cramps. Botulism in a wound causes inflammation around the wound, followed by low blood pressure and circulatory collapse.

Can botulism grow in alcohol? ›

How can pruno give me botulism? When people make pruno, they usually ferment fruit, sugar, water, and other common ingredients for several days in a sealed plastic bag. Making alcohol this way can cause botulism germs to make toxin (poison).

Can botulism form in the fridge? ›

There seems to be a myth that open tins in the fridge cause botulism, but it isn't true. Botulism is a rare & life-threatening condition caused by Clostridium Botulinum bacteria. These toxins attack the nervous system causing paralysis. But, a little anecdotal research quickly clears this myth up.

Can garlic cause botulism? ›

BOTULISM WARNING

As with all low-acid vegetables, garlic will support the growth and subsequent toxin production of the bacterium Clostridium botulinum when given the right con- ditions. These conditions include improper home canning and improper preparation and storage of fresh herb and garlic-in-oil mixtures.

How easy is it to get botulism? ›

Botulism is not transmitted from person to person. Botulism develops if a person ingests the toxin (or rarely, if the toxin is inhaled or injected) or if the organism grows in the intestines or wounds and toxin is released. Food-borne botulism is spread by consuming food contaminated with the botulism toxin or spores.

How do adults usually get botulism? ›

Botulism does not spread from person to person. A person can get foodborne botulism from eating food that contains botulism toxin if the food is not heated or processed properly. Foodborne botulism is most frequently caused by eating improperly processed home-canned, preserved or fermented foods.

What are naturally poisonous foods? ›

Cassava, sorghum, stone fruits, bamboo roots and almonds are especially important foods containing cyanogenic glycosides. The potential toxicity of a cyanogenic plant depends primarily on the potential that its consumption will produce a concentration of cyanide that is toxic to exposed humans.

Can you get botulism from nuts? ›

So, if you remove the oxygen by vacuum sealing and store at room temperature, you have created a nearly perfect set of conditions for Clostridium botulinum to grow and produce toxin. Other foods, like nuts, grains, or properly prepared jerky, can be stored safely by vacuum sealing.

Can you get botulism from cheese? ›

The majority of cases of botulism caused by dairy products are related to cheese products specifically. Epidemic outbreaks and isolated cases have been reported over time. Domestically canned foods are still among the primary causes of the disease.

Can you smell botulism? ›

Foodborne botulism is a rare but serious illness caused by eating foods that are contaminated with the disease‑causing toxin. You cannot see, smell, or taste botulinum toxin – but taking even a small taste of food containing this toxin can be deadly.

Does Salt prevent botulism? ›

Added solutes (salt or sugar) grab a portion of the water in your food, limiting its availability to the microbes. A concentration of about 10% salt will effectively prevent germination of Botulism spores in your canned food.

How common is botulism in honey? ›

Honey is one of the most common sources of botulism. About 20 percent of botulism cases involve honey or corn syrup. One 2018 study looked at 240 multifloral honey samples from Poland. The researchers found that 2.1 percent of the samples contained the bacteria responsible for producing the botulinum neurotoxin.

Who is most at risk for botulism? ›

People at Risk
  • People who inject certain drugs, such as black tar heroin, put themselves at greater risk of getting wound botulism.
  • People who drink certain kinds of alcohol they make themselves, such as prisoners who drink “pruno” or “hooch” made in prisons, put themselves at greater risk of getting foodborne botulism.

Can botulism be killed by cooking? ›

Normal thorough cooking (pasteurisation: 70°C 2min or equivalent) will kill Cl. botulinum bacteria but not its spores. To kill the spores of Cl. botulinum a sterilisation process equivalent to 121°C for 3 min is required.

Can cooked garlic cause botulism? ›

Home-prepared garlic oil creates a low oxygen environment, and garlic is low in acid; the combination creates a high-risk food for botulism for everyone, not just baby. Never keep homemade garlic oil at room temperature, avoid serving baby garlic oil (even if it has been refrigerated) and avoid garlic confit entirely.

Can you test food for botulism? ›

The new test provides a rapid, preliminary screening in the event of a bioterrorist threat, an outbreak of foodborne botulism in which the culprit food has not yet been pinpointed, or during other emergencies. The strip fits snugly into a holder like those in pregnancy test kits for at-home use.

What happens if you eat botulism? ›

How do you test for botulism? ›

To diagnose botulism, your health care provider checks you for muscle weakness or paralysis. Your provider looks for symptoms such as drooping eyelids and a weak voice. Your provider asks about foods you've eaten in the past few days. They try to find out if you were exposed to any bacteria through a wound.

Can you survive botulism? ›

When your case is mild, you may need weeks or months for a full recovery. It may take months or years to completely get over a very serious case. If the illness isn't treated, botulism can be life-threatening. But people recover in about 90% to 95% of cases.

Can botulism grow on dirty dishes? ›

In the very unlikely event of contamination, the spores will die on your sink and other dishes, because they will be in contact with air. If you are still nervous, fill your sink, together with the dishes, with just-boiled water. The toxin itself is neutralized after 10 minutes at 80 celsius.

Can botulism grow in Tupperware? ›

Clostridium botulinum bacteria grow in dirt. Their spores can wind up on potatoes and other vegetables and then, when conditions are right, the bacteria can grow like mad, producing the deadly toxin. The bacteria don't like oxygen, so a sealed container is just dandy for them.

Can you get botulism from drinks? ›

How Can I Get Foodborne Botulism? You can get foodborne botulism by eating food or drinks contaminated with the botulism toxin. Foodborne botulism occurs when Clostridium botulinum bacteria grow and produce toxin in food or drinks that have not been sufficiently heated or cooked to inactivate the toxin.

What temperature does botulism grow? ›

botulinum will grow at temperatures as low as 38°F (3.3°C). As was previously noted, maintenance of temperatures below 38°F (3.3°C) after the product leaves your control and enters the distribution system cannot normally be ensured.

Can dehydrated food have botulism? ›

Many people wonder if you can you get botulism from dehydrating. The answer is no – because the botulism bacteria needs moisture in order to reproduce. So once a food is adequately dried, botulism is not an issue.

Can botulism grow in plastic containers? ›

Even a plastic or glass container without a lid may allow the botulism germ to grow in the bottom of the container. It's very important for fresh air to move around the fermenting foods, because botulism grows in an environment without air circulation – such as plastic or glass containers.

Can botulism grow in the freezer? ›

Freezing does not destroy Clostridium botulinum, the spoilage organism that causes the greatest problem in canning low-acid foods, such as vegetables and animal products. However, Clostridium botulinum will not grow and produce toxin (poison) at correct freezer temperatures (0° F or below).

Is garlic in olive oil safe? ›

Garlic in oil is very popular, but homemade garlic in oil can cause botulism if not handled correctly. Unrefrigerated garlic-in-oil mixes can foster the growth of clostridium botulinum bacteria, which produces poisons that do not affect the taste or smell of the oil.

Can you get botulism from oil? ›

Oils that are flavored with fresh herbs or garlic can be a source of food-borne illness—specifically botulism.

Can you get botulism from butter? ›

Although mostly fat, butter is a low-acid food. Butter, milk and cream (like meat and vegetables) are low-acid products that will support the outgrowth of C. botulinum and toxin formation in a sealed jar at room temperature.

Can you get botulism from hot sauce? ›

Although hot sauces may not necessarily be water-bath canned, they are typically bottled and most likely will have an anaerobic environment that would be conducive to the growth of clostridium botulinum.

Can the pink sauce give you botulism? ›

Pink Sauce may cause botulism, a rare but fatal illness caused by a toxin produced in a bacteria called Clostridium botulinum. The toxin targets the nervous system, which can inevitably lead to paralysis and respiratory failure.

How is botulism cured? ›

Doctors treat botulism with a drug called an antitoxin, which prevents the toxin from causing any more harm. Antitoxin does not heal the damage the toxin has already done. Depending on how severe your symptoms are, you may need to stay in the hospital for weeks or even months before you are well enough to go home.

How do you get botulism from potatoes? ›

If a low-acid food such as potato soup is stored unrefrigerated in an anaerobic environment (e.g., a sealed container), without a barrier to bacterial growth, spores can germinate, resulting in bacterial growth and botulinum toxin production (2).

Can you get botulism from frozen tomatoes? ›

Expert Response. "Freezing does not destroy Clostridium botulinum, the spoilage organism that causes the greatest problem in canning low-acid foods, such as vegetables and animal products. However, Clostridium botulinum will not grow and produce toxin (poison) at correct freezer temperatures (0 degrees F or below).

How can you tell if food has botulism? ›

You cannot see, smell, or taste botulinum toxin – but taking even a small taste of food containing this toxin can be deadly.
  1. The container spurts liquid or foam when you open it.
  2. The food inside is discolored, moldy, or smells bad.
6 Jun 2019

Can botulism be killed by cooking? ›
