The source of the family’s botulism food poisoning was a mix of canned tomatoes and green beans. During the course of two days, the family ate chicken, canned tomatoes, and canned green beans. The spinach salad contained botulism toxin. So what was the family eating before and after the food contaminated them? Read on to find out.

Case 3’s wife

The family members all experienced abdominal pain, bloating and diarrhea a day or so after eating a large meal prepared by the husband and his wife. The symptoms progressed to blurred vision, diplopia and dry mouth. Ten days later, they went to the emergency department of St. Michael’s Hospital with more severe symptoms. They drank water constantly from a bottle and had a weakened gag reflex.

The symptoms and course of each patient’s disease were confirmed by laboratory studies. Stool samples from Case 3’s wife contained C botulinum type B, which should not be recovered from normal stool. Moreover, stool cultures from five other individuals tested negative for botulinum toxin. The stool sample from case one was not sent for examination, since it was taken as a result of obstipation secondary to paralytic ileus.

Home-canned tomatoes

An outbreak of botulism food poisoning of type B was confirmed in Ontario in January 1999, and the suspect food was home-canned tomatoes. Although the outbreak was limited to one case, it highlighted the importance of proper home-canning techniques and the need for early detection of the disease. Most cases of botulism produce symptoms that are similar to gastrointestinal illness, including descending paralysis, extraocular palsies, and ptosis. However, other symptoms may include gastrointestinal distress, coma, and even autonomic dysfunction.

The toxin produced by botulism is undetectable by sight, smell, or taste. It is difficult to identify the presence of botulism, but cans that have deformities are likely contaminated with botulism. During the canning process, food is kept at temperatures between 50 and 70 degrees Fahrenheit. Most types of canned foods should be consumed within a year of their preparation, but if the date is older than this, it is best to discard it. The Centers for Disease Control and Prevention offers a list of steps to take if suspecting food is contaminated with botulism.

Raw vegetables

The most common cause of food borne illnesses is bacteria. Only about 20 species of e. coli cause food poisoning. They live naturally on fruits, vegetables, and meat, but only when they are not properly prepared, can they cause illness. Proper cooking and handling destroy these bacteria and prevent their re-contamination. However, some people are prone to the disease. Here are some tips to keep in mind when preparing food and preventing botulism.

A person suffering from botulism should immediately seek medical treatment. There are antitoxins available to prevent respiratory failure and help patients recover. If the condition is severe, the person may need a ventilator and intensive medical care. Botulism outbreaks can be highly dangerous for the public’s safety, which is why it is vital for physicians to report suspected cases immediately. Moreover, this way, physicians can quickly identify and treat related cases.

Home-canned vegetables

Botulism, a type of bacterial infection, is a contaminant that can easily hide in many foods. Low acidity foods like tomatoes, peaches, and vegetables are easy to infect with botulism spores. Inappropriate canning methods may also cause botulism. Cases of botulism in the United States have involved canned vegetables, garlic in oil, tomato sauce, carrot juice, and canned soup.

Botulism is rare but potentially deadly. It is transmitted through the foods we eat, contact with soil, or an open wound. The toxin produced by Clostridium botulinum bacteria weakens nerves in the body. The symptoms often start in the face and then spread to the torso, arms, and legs. Ultimately, the body becomes weak, and the symptoms can even lead to death. If you experience any of these symptoms, see a health care provider immediately.

C botulinum spores on surfaces of raw vegetables

In the early 20th century, the spores of Clostridium botulinum were found almost everywhere-on the surfaces of raw vegetables, in rivers and lakes, and in the intestines of fish. Scientists discovered that the spores were durable, even in low-oxygen environments. The resulting food poisoning was fatal, and researchers sought to find a cure.

The spores of C. botulinum are ubiquitously present in the environment, including soil and spices. The bacterium is a spore, and survives normal cooking as a heat-resistant spore. If stored at the wrong temperature, the spores can grow rapidly and cause illness. The most common foods affected by botulism are starchy vegetables and fruits.


The symptoms of botulism poisoning usually begin within a day of exposure. The family contracted botulism after eating canned tomatoes, spinach salad, and green beans. The disease can be prevented with special care during the preparation of food. While there are some symptoms that are not common, detecting botulism in time can save a family from a devastating outbreak. Fortunately, botulism is not contagious and can be prevented with proper food storage and preparation techniques.

The bacteria that causes botulism is typically found in soil. C. botulinum is commonly found on green beans. The bacteria can survive in improperly canned beans, but are unlikely to grow in tomatoes, which are acidic. Nevertheless, the family infected with botulism likely ate the canned tomatoes that were contaminated. This outbreak is a great example of how food safety is paramount, and should be practiced by everyone.
