Under a high magnification of 10431X, half that of PHIL 10566, this scanning electron micrograph (SEM) revealed a colony of Gram-negative bacilli, or rod-shaped Salmonella sp. bacteria. The genus Salmonella is a member of the taxonomic family, Enterobacteriaceae, and approximately 2000 serotypes of this genis are known to cause disease in human beings.
How do people catch Salmonella?
Salmonella live in the intestinal tracts of humans and other animals, including birds. Salmonella are usually transmitted to humans by eating foods contaminated with animal feces. Contaminated foods usually look and smell normal. Contaminated foods are often of animal origin, such as beef, poultry, milk, or eggs, but any food, including vegetables, may become contaminated. Thorough cooking kills Salmonella. Food may also become contaminated by the hands of an infected food handler who did not wash hands with soap after using the bathroom.
