Canned foods are an indispensable part of modern kitchens due to their long shelf life and easy accessibility. However, this practical method of food preservation comes with risks. In particular, improperly processed or stored canned food can cause food poisoning, such as botulism, which can lead to serious health problems. Symptoms of canned food poisoning often appear quickly and severely, so it is vital to recognize the signs and take preventive measures.

Symptoms of Canned Food Poisoning

Canned food poisoning is a serious type of food poisoning known as botulism, which is usually caused by toxins produced by the bacterium Clostridium botulinum. Botulism can be life-threatening, requiring rapid intervention. 

Nausea and Vomiting: One of the early symptoms of canned food poisoning is nausea and vomiting.

Abdominal pain and cramps: Severe abdominal pain and cramps may occur.
Diarrhea or Constipation: Digestive system problems can manifest as diarrhea or constipation.
Fatigue and Weakness: Extreme fatigue, weakness and weakness may occur.
Visual Impairment: Vision problems such as double vision, blurred vision and drooping eyelids.
Dry mouth and difficulty swallowing: Dry mouth and difficulty swallowing are symptoms of botulism.
Breathing Difficulty: Breathing may become difficult due to the respiratory muscles being affected, which requires emergency intervention.
Muscle Weakness and Paralysis: Muscle weakness and paralysis can spread throughout the body, starting from the muscles of the face and neck.

Things to Watch Out for in Canned Foods

It is important to take some precautions for the safe consumption of canned foods. Here are some points to consider:

Condition of the Can: Avoid cans that are swollen, cracked, leaking or rusted. These conditions can be a sign of bacterial contamination.
Condition of Lid: Canned food with a bulging lid is a sign of gas buildup and bacterial activity inside.
Odor: If a foul odor is emitted when the can is opened, do not consume it. This indicates that the food has spoiled.
Color and Texture: Do not consume if the food is different from its normal color or if there are changes in texture.
Date and Labeling: Pay attention to the canned food's expiration date and production information. Do not consume expired products.
Hygienic Conditions: Pay attention to hygiene rules when preparing canned food. Sterilization is important if you are canning at home.
Storage Conditions: Store canned food in a cool, dry and dark place. Excessive heat, humidity or light can cause canned food to spoil.
Boiling: Boiling homemade preserves for 10 minutes before consumption can neutralize botulinum toxins.
