Experiment 21: Salmonella and food contamination Purpose /Objective Objective: To test salmonella in spinach sample over five lab periods. Food contamination of salmonella can cause serious illness. Only small numbers of salmonella need to be found for a food product to be considered contaminated. Tests used Pre-enrichment- lactose broth Selective enrichment broth- with Tetrathionate Brilliant Broth Selective Plating- Brilliant Green Agar Isolation of salmonella conformation- is preformed

Salmonella Salmonella is a rod shaped‚ gram-negative bacteria‚ which infects humans and other mammals. It is the most common cause of food poisoning and the leading cause of Salmonellosis. Salmonella infects more than 40‚000 people a year in the US and causes 400 deaths a year. It is caused by consuming raw or undercooked food‚ having contact with a person or animal that is infected by salmonella‚ and poor kitchen hygiene. Symptoms of salmonellosis include diarrhea‚ fever and abdominal cramps

for Disease Control and Prevention says (CDC) “In America about 40‚000 cases of Salmonella are reported every year”. When you hear salmonella you only think salmonella but you really don’t understand what it is. “Salmonella is a bacterium that occurs in the intestines‚ that causes food poisoning”. When contracting the virus there are common symptoms you attract. Christian Nordavist says when infected with Salmonella it causes “typhoid fever‚ gastroenteritis‚ enteric fever and other illnesses”.

What does their name mean? There is a great deal of confusion over the naming of Salmonella strains (even the people who work on Salmonella are confused!) but in essence‚ the strains which we will deal with here are generally different serovars of Salmonella enterica. This means that they all belong to the genus Salmonella‚ a division that groups similar‚ though not identical bacteria together. These bacteria are named after the scientist who discovered them‚ Dr. Daniel Salmon. The majority

Michael J Jordan SCI/163 Professor Gild July 24‚ 2013 Salmonella Salmonella is a common bacterial disease that affects the intestinal tract. It commonly lives in human and animal intestines and are shed through feces. Humans are affected by it mostly from contaminated food or water sources.

A lot of times‚ it is a simple matter of just being careless‚ or ignorant of the facts‚ that causes a person to get sick from the foods or animals that they handle. One type of bacteria that can be picked up from these bad practices is Salmonella. If left unchecked‚ or if action isn’t taken‚ then this bacteria has the potential to develop into an illness

1. Salmonella enteritidis is a gram-negative bacterium that causes food-borne illnesses‚ and is the most commonly known serotype of Salmonella. It is a constant problem because of the misuse of antimicrobials in farms‚ disease treatment‚ growth promotion in domestic livestock‚ and the increasing problem of antimicrobial resistance. Current research is being conducted with bacteriophages because they have been identified as a prospective alternative bio-control method to control Salmonella contamination
