1. What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite.
Salmonellosis is a type of food poisoning found in humans caused by the Salmonella bacterium. There are many types of these bacteria such as Typhimurium and Enteritidis which are the most common serotypes found in the United States. Salmonella is a facultative anaerobic bacterium in the family of Enterobacteriaceae. The principal habitat for Salmonella is in the intestinal tract of humans and other animals. Most infections of Salmonella are a result of ingesting contaminated food or water. Those with weaker immune systems such as children and elderly are more likely to get salmonellosis.
Salmonella may be found in places other than food. It can be found in the feces of some pets, especially those with diarrhea. Reptiles, baby chicks and ducklings, hamsters and other rodents are likely to carry Salmonella.
2. How is this infectious agent transmitted through food or water?
Salmonellosis is the most common foodborne illness in the United States. Every year 40,000 cases of Salmonellosis are reported and many milder cases are not diagnosed. Salmonellosis is caused by eating foods or drinking water contaminated by salmonella. Food may be contaminated by food handling or food processing. A frequent cause is when a food handler does not wash their hands with hot water and soap after using the bathroom.
Beef, poultry, unpasteurized milk and juice, and raw or undercooked eggs are the most common to be contaminated with salmonella, but raw vegetables and fruits can also become contaminated. These foods can become contaminated from unsafe food storage practices and unsafe cooking procedures. These foods may look and smell normal.
