Clostridium Botulinum on Canned Food

What is Clostridium Botulinum? What’s the does Clostridium Botulinum have to do with Canned Food? What are the effects and symptoms that will be experienced if infected by Clostridium Botulinum? How to identify if the canned food that we are going to consume is safe from Clostridium Botulinum? Let’s Find Out!

What is Clostridium Botulinum?

Clostridium Botulinum is a bacterium that can produce toxins in food, wounds, and the intestines that attack the nervous system. The disease caused by the Clostridium botulinum is called botulism.

Clostridium Botulinum can be found in dust, soil, rivers, or the seabed. This bacterium is harmless under normal environmental conditions, but Clostridium Botulinum can release its toxins if it is in an oxygen-starved environment. For example, when in closed cans, bottles, in the human body, mud and soil that does not move.

Symptoms of Botulism

Although Botulism is a very rare disease, it is a serious disease that is very dangerous and deadly. Symptoms of Clostridium Botulinum poisoning will occur 18 to 36 hours after the poison enters the body.

Botulism attacks the nervous system and can cause disorders of the muscles, respiratory and digestive systems. Botulism can cause death if not treated promptly.


Symptoms of botulism that occur due to food poisoning are:

      Difficulty swallowing and speaking

      Dry mouth

      Weak facial muscles

      Visual impairment

      Weak eyelids (drooping)

      Difficulty breathing



      Stomach cramps


Clostridium Botulinum and Canned Food

Where other bacteria cannot thrive in an oxygen-starved environment, Clostridium Botulinum bacteria thrive and release its toxins when under oxygen-deprived and under acidic conditions.

This condition puts canned food at risk of being infected by Clostridium Botulinum.

It is recommended not to consume or try any canned food that has the following conditions:

  1. Leaking, bulging, or badly dented cans
  2. Canned food with a foul odor
  3. Cracked jars or jars with loose or bulging lids
  4. Any container that spurts liquid or foam when opened

How to prevent Clostridium Botulinum‘s contamination

How to prevent Clostridium Botulinum‘s contamination, here are the recommendations:

Tips for consumers:

  1. Store canned foods at the right temperature
  2. Consume immediately after the can opened
  3. Don’t eat food whose packing has been damaged (for example : dents, leaks)

Tips for food manufacturers:

  1. Do a Clostridium Botulinum test before the product go to market
  2. Regularly do food tests before going to market

How to test Clostridium Botulinum on Food?
