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.

12 Foods that can cause deadly botulism (3)

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.

(Video) I could have died if I ate this stew. (Botulism poisoning)

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.

(Video) Stop Bot 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)

Jar of honey – A morgueFile Free photo

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.

Jan 14, 2020

What does botulism need to grow? ›

A pH near 7 or neutral favors the growth of Clostridium botulinum, while growth is inhibited at a pH of 4.6 or lower. The pH of a food also influences the amount of heat needed to kill C. botulinum spores; the higher the pH, the greater the level of heat needed.

Can botulism grow in peanut butter? ›

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.

How do adults 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.

Can you taste or smell botulism? ›

Protect Yourself from 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.

What two organs 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.

What kills botulism? ›

botulinum spores can be killed by heating to extreme temperature (120 degrees Celsius) under pressure using an autoclave or a pressure cooker for at least 30 minutes. The toxin itself can be killed by boiling for 10 minutes.

Can your body fight off botulism? ›

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.

Who is the most common victim of botulism? ›

Intestinal botulism is the most common form of botulism. Children under the age of 12 months are most susceptible, but adults who have certain gastrointestinal problems may also be at risk.

What temperature kills botulism? ›

botulinum can only be destroyed under proper temperature and pressure for sufficient time. Temperatures in the range of 240°F to 250°F (115°C to 121°C) are needed in order to kill spores (USDA 2015).

How much botulism is fatal? ›

Botulinum toxin is one of the most powerful known toxins: about one microgram is lethal to humans when inhaled.

Can botulism grow in sugar? ›

Thus, for safety against this pathogen and others, store food items below 41°F (5°C) and hold hot food above 135°F (57°C) (FDA 2013). Due to their low water activity, dehydrated foods and foods high in salt and/or sugar do not support growth of C. botulinum.

Which bacteria is most often associated with contaminated home-canned foods? ›

Why is it found in canned goods? The bacteria Clostridium botulinum releases the toxin that causes botulism as part of its natural anaerobic process, meaning it multiplies in an oxygen-free environment, like a sealed can, Schaffner said.

How do you get botulism from potatoes? ›

Baked potatoes that have been wrapped in foil have been linked to cases of botulism. Clostridium botulinum spores can survive the baking process and the foil wrap seals the potato preventing oxygen from being present.

Does all honey contain botulism? ›

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 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.

Does Karo syrup cause botulism? ›

Karo syrup is also unsterilized, meaning that it contains bacteria that can cause botulism in younger children and infants.

Can you get botulism from apples? ›

Tips for safe home canning

C. botulinum is inactive in high-acid environments. This includes canned fruits and fruits products like applesauce and fruit jam, and vegetable products with added acid, such as when making pickles, relish, and canned tomatoes.

Can you get botulism from peaches? ›

Botulism spores are weak

They are weak in that something simple like the acidity of strawberries, or peaches, or pickles, immobilizes them. The acid won't kill them, but, they can't grow (germinate) in high-acid environments and because they can't, they can't produce their deadly toxin (which we'll discuss next.)

Can you get botulism from a Mason jar? ›

Store jars without the ring. Metal to metal can rust and even a pinhole of air can enable bacteria to grow. If there is any botulism in the jar, it can make you very sick or even lead to death.

Can you get botulism from canned tomatoes? ›

Because of their acidic nature, tomatoes are an uncommon food to cause botulism. To improve their taste, however, some varieties of tomatoes are bred to have low acidity. This alteration may cause the pH to be just high enough to allow for the growth of C botulinum and the production of its toxin.

Can botulism grow in alcohol? ›

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 you get botulism from pickles? ›

Making sure enough vinegar is added to the cucumbers is important to make safe pickles; Clostridium botulinum can grow in improperly canned, pickled foods with a pH higher than 4.6.

Can you get botulism from fruit? ›

What type of food is botulism found in? ›

Low-acid foods are the most common sources of botulism linked to home canning. These foods have a pH level greater than 4.6. Low-acid foods include most vegetables (including asparagus, green beans, beets, corn, and potatoes), some fruits (including some tomatoes and figs), milk, all meats, fish, and other seafood.

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.

Is botulism only in canned foods? ›

We usually associate foodborne botulism with foods improperly canned at home, but other foods also have been implicated.
