Staphylococcal-poisoning
This is the most common type of food-poisoning caused due to the food contaminated with a potent toxin, namely, enterotoxin. This toxin is produced by certain strains of Staphylococcus aureus. A sudden onset of illness starts usually within 3 to 6 hours after ingestion of the contaminated food.

Source. These bacteria are commonly present on the skin, nose and other parts of human body. People who handle foods carelessly usually transfer them to the food. Foods most commonly contaminated involve those which are eaten cold, e.g., cold meat, poultry, salads, bakery products, etc.

Symptoms. As said earlier, the disease starts within 3 to 6 hours after ingestion of the contaminated food and is manifested by nausea, vomiting, abdominal pain and diarrhoea within 24 to 48 hours. If the case becomes severe, dehydration and collapse may follow. However, in usual conditions death is rare.

Control. The disease can be controlled by preventing the entry of the bacteria to food. It is important that all susceptible foods are kept under refrigeration to restrict the growth of the bacteria; and also by the destruction of the bacteria by heat.
