Salmonella
Fig 1. Salmonella Bacteria
The first thing to note about Salmonella (seen in Fig. 1) is that it is a bacteria, and therefore a living organism. However the term "Salmonella" is used loosely in daily conversation to specify an illness caused by that bacteria in humans, and in other animals. Most people have some vague recollection of a "salmonella outbreak" caused by a contaminated food supply being reported in the media, and some people may have contracted Salmonellosis, which is technically the name of the human disease. Salmonella is just the organism that causes it. But because Salmonella is a form of life it needs to be understood environmentally, and so I would propose addressing it on each individual environmental level, as specified in this concept map:

In other words, we need to examine the life cycle of the individual bacteria. Then we need to understand how it infects an individual host, whether human or animal. The effects of Salmonella infection on the larger population then have to be taken into account, considering larger questions such as vectors of transmission and ways of preventing large-scale outbreaks. But because Salmonella is regularly in the news, we need to address the issues that students may have already heard of -- can't you "catch Salmonella" from eating eggs? Wasn't there some local restaurant that killed somebody with Salmonella? So finally these more domestic concerns will be addressed, by considering Salmonella infection as a medical matter, on both the micro- and macro-cosmic levels of how an individual might avoid infection, and what news of a Salmonella outbreak might actually mean.
Salmonella is a type of anaerobic bacteria, which require no oxygen to survive. In fact...
Salmonella Food-born illness Food-borne illnesses: Salmonella The salmonella bacterium is one of the most well-known and well-publicized health threats in the U.S. "Salmonella germs have been known to cause illness for over 100 years" (What is Salmonellosis, 2010, CDC). Salmonella bacteria can be present in the intestines of humans, and can be transmitted through consumption of tainted foods, water, or animal matter. Infections can be difficult to trace in the early stages, because
The symptoms of salmonella include fever, diarrhea, and abdominal cramps that appear about 12 to 72 hours after infection. The illness can last 4 to 7 days, and most people recover without treatment. It is most dangerous for the elderly, infants, and in people with certain other health disorders. After the FDA announced the outbreak, large restaurant chains like McDonald's, Taco Bell, Burger King and many others immediately pulled all their
Salmonella Salmonellosis is an infection with bacteria called Salmonella. Salmonella germs have been known to cause illness for over 100 years. The bacteria were first isolated in 1885 by Theobald Smith from pigs. The genus name was derived from the last name of D.E. Salmon, who was Smith's director. In 1896 Salmonella infection was diagnosed in humans. Salmonella is the genus name for over 2,500 types of bacteria. Though each type
Salmonella Infection The salmonella bacteria had been the twentieth century’s archetypical organism causing food poisoning, highly notorious for the 1988-89 crisis of salmonella in eggs. By that time, however, it had already been a topic of scientific and public health focus for more than a hundred years. Previously linked to animal foods, phage typing’s introduction during the 1940s started revealing the complex nature of its associations with its environment (Hardy, 2004). Epidemiological
Food Borne IllnessesThe food borne investigations conducted by CDC in 2021 showed that most outbreaks were associated with salmonella pathogen. The said pathogen and related infections were associated with foods inclusive of, not limited to; ground turkey, cashew Brie, prepackaged salads, onions, and seafood. Individuals whose immunity has been weakened by diseases like cancer and kidney disease as well as their treatments are more likely to get salmonella infections (CDC,
Foodborne illness at hand was a salmonella outbreak at a buffet at the Old Country in Cheyenne, Wyoming (Flynn, 2016). The cause of the salmonella outbreak is not known, but salmonella is a common risk associated with buffets in particular. The risk occurs because warm food is a fertile breeding ground for the salmonella bacteria. Cooking helps to destroy the bacteria, so improper heating is a critical issue, which makes
