In many cases, the source of salmonella poisoning has been traced to poultry products, and particularly to hens' eggs and chicken meat. The infection of eggs can originate in the hen's ovaries or it may occur as a result of fecal contamination via the egg shell.
Symptoms of salmonella poisoningSymptoms of salmonella food poisoning usually appear suddenly 12–24 hours after infection and include headache, nausea, abdominal pain, diarrhea, and sometimes fever. They usually last for only two or three days, but in severe cases dehydration or septicemia (blood poisoning) may develop, especially in the very young and old.
Treatment and preventionTreatment is by rehydration therapy to replace lost fluids. In severe cases, fluid may need to be replaced by means of intravenous infusion.
In general, it is advisable to avoid foods that contain raw egg (such as homemade mayonnaise, mousses, and ice cream). The risk of infection is reduced in very fresh eggs. Salmonella organisms are not killed by light cooking, and eggs given to children or the frail or elderly should be well cooked.
