Food Poisoning

What is Food Poisoning?

Food poisoning is also known as a food-borne illness, caused by eating contaminated food. The most common cause of contamination is the presence of infectious organisms. They are present and breed in food when incorrectly cooked. It is a common infectious disease that affects people every day. Around 3,51,000 people across the globe die of food poisoning every year.


The onset of food poisoning symptoms may occur within 4 hours of eating contaminated food. In some cases, it could also begin in half an hour. These symptoms normally resolve in 1 - 2 days, without any complications or life-threatening problems. It is not easy to recognize the symptoms of food poisoning as they are quite similar to those of other diseases. A few common symptoms are:

  • Feeling sick.
  • Vomiting.
  • Diarrhoea.
  • Stomach cramps.
  • Lack of energy and weakness.
  • Abdominal pain.
  • Loss of appetite.
  • High temperature.
  • Chills. 


Food poisoning is caused by eating contaminated food. Food infected with bacteria, virus, and parasitic agents start food poisoning.


Some risks of food poisoning are:

  • Irritable bowel syndrome.
  • Kidney failure.
  • Lactose intolerance.
  • Reactive arthritis.
  • Pericarditis.
  • Guillain-Barre syndrome.


Following are some methods that can be used to prevent food poisoning:

  • Refrigerate perishable food.
  • Throw food when in doubt.
  • Wash your utensils and hands nicely.
  • Separate raw food from ready-to-eat food.
  • Cook food at a proper temperature.
