For the module 1 SLP, we’re going to take a brief look at Salmonella and some of the factors that play a role in a foodborne outbreak. We’ll look at etiologic agent, host factors, and environmental factors as well as host factors and how they can play a role in the occurrence. First and foremost, we need to see what salmonella is and then we can break it down when we look at the other factors.
Salmonella is a bacterial disease that occurs in the intestines, the signs and symptoms can be; fever, or other illnesses such as diarrhea and abdominal cramps. People typically get salmonella from contaminated foods, which seems to occur frequently from poultry and eggs (Nordqvist, 2016). This is just a basic look at salmonella though, next we need to look at the epidemiologic triad (host, agent, and environment) and see how each plays a role in a salmonella outbreak.
First the etiologic agent of salmonella; Salmonella gastroenteritis is the infectious agent that causes salmonella. It is transmitted through vehicle transmission, meaning it travels from place to place on something (contaminated meat for example).

What if it were a host that had salmonella from the beginning? If a patient presents with all the signs and symptoms, but it isn’t due to food handling then you’d have to assume that there is an outside factor. According to the Mayo Clinic article on salmonella there are a few factors where a host can increase their chance of getting salmonella. These factors include; international travel, specifically to countries with poor sanitation, owning a bird or reptile that is infected with the bacteria and handling that animal routinely increases your change for exposure. Additionally use of antacids and antibiotics can create a perfect environment for the bacteria to grow in your intestines (Mayo Clinic,
In the case of the Salmonella gastroenteritis outbreak after a reception, the origin of the illness comes down to the potato salad served at this event, however, the investigators are not certain of the mechanism of contamination. Whether the service worker (infected) might have unknowingly contaminated the food item or whether the food service worker also was infected through the same source as the case-patients remains unclear.2 Because the mechanism is unclear, it’s hard to identify if any of the ingredients in the potato salad were the culprit. In many cases, however, investigators are able to identify the mechanism for contamination.
This case study, finalized and updated onto the Centers for Disease Control and Prevention, talks about the Multistate Outbreak of Salmonella Wandsworth Infections Linked to Veggie Booty. Publishing this outbreak onto their website makes it very beneficial and helps the public realize the importance of food health. Food health is just as important as overall public health. It is essential because people need to consume food in order to live, and if their food is tainted or contaminated, it would cause health problems and sickness and in some extreme cases, death. Ensuring food health will overall promote public health in the long run.
In the article Backyard Chickens Carry Hidden Salmonella by Aneri Pattani. She explains why 900 people are infected with salmonella and the chickens are not the culprits of this disease. The normal issue with contracting Salmonella is normally eating raw cookie dough or undercooked eggs or meat. But it can also be contract when people put objects that came in contact with their live poultry, or when they deal with their live poultry and touch their mouth. Dr Nicholas says “ this doesn't mean people are not supposed to have Backyard chicken, but it is very important to wash your hands and make sure you have separate clothes for when you're dealing with live poultry”. She advised to not let your outside birds live with you in your house and avoid
What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite.
Norovirus and Salmonella are the two most common pathogens, resulting in the most hospitalizations and deaths. Norovirus is a pathogen that infects the stomach and intestines by causing inflammation. Symptoms of norovirus include; nausea/vomiting, diarrhea and stomach pain leading to dehydration causing one to urinate more frequently and feel dizzy while standing up. In order to avoid contracting the Norovirus, the CDC recommends thoroughly washing fruits, vegetables and cooking seafood to appropriate temperatures, which can survive up to 140 degrees Fahrenheit (https://www.cdc.gov/norovirus/preventing-infection.html). Salmonella affects the gastrointestinal tract when bacteria is swallowed, mainly coming from raw food products; eggs,
Most people know that Salmonella is a bacteria that infects people heavily through uncleaned and poorly prepared food. However, few people know that this disease can actually be caused by bacterial infection in their well water. Although Salmonella is very rarely a deadly disease, it can still cause extreme diarrhea, high fevers, and cramps. Eliminate this threat by understanding how your well water gets infected and what you can do to treat it.
Exposure to salmonella is not taken lightly, as it can prove deadly and lead to contact with several related diseases such as salmonellosis. Salmonellosis can manifest with symptoms including diarrhea, severe cramping, and
Gastrointestinal diseases are pervasive problem that is caused by ingestion of contaminated foods or water in which an extensive etiological agents known as enteric pathogen are present, [1]. Salmonella is one of the most opportunistic gram negative, facultative anaerobic food borne pathogens that represent a major health problem and a substantial cause of food poisoning[2]. Salmonellosis caused by Salmonella enterica serovar Typhimurium (S. Typhimurium) stance as the second most prevalent cause of acute gastroenteritis that affecting one million illnesses in the United States, with 19,000 hospitalizations and 380 deaths[3]. Infection begins with the ingestion of contaminated food or water then characterized by attachment of the bacteria by fimbriae or pili to cells lining the
Salmonella enterica: is a member of the Enterobacteriacecae family, a rod shape Gram-negative bacterium. After passage through the gastric acid barrier, S. enterica binds tightly to specific receptors of the epithelial cells in small intestine. The receptor interaction activates a cellular response results in transfer of bacterial effector proteins into the epithelial cell, following by uptake of bacterial cell by endocytosis. Invasion of epithelial cells induce an inflammatory response that increases the fluid secretion of epithelial cells, causing diarrhea. [2]
Typhoid fever. One of the types of salmonella bacteria is known as salmonella typhi. Even if salmonella is not originally carried by chickens, infected food handlers might contaminate the food during preparation and an undercooked chicken can absorb the bacteria and spread the disease. Around 21.5 million cases of typhoid fever is recorded worldwide. Symptoms of typhoid fever include a very high fever, weakness, headache, stomach pain, and rash.
There have been numerous times where I have been affected by Salmonella, so it was easy to swing towards Salmonella as the CBRN choice. Salmonella is found in everyday food products such as raw chicken, raw beef, raw fish, raw eggs and unpasteurized milk (foodsafety.gov). Salmonella can also be found on reptiles, amphibians, birds and even pet treats (foodsafety.gov). People will start to feel symptoms within four to seven days which include: nausea, vomiting, abdominal pain, diarrhea, fever, headaches, dehydration and possibility blood in the stool (mayoclinic.gov).
It is important in the way food is handled and the safety of the process that food goes through. One of the most common causes of food poisoning is bacteria and viruses. Symptoms of food poisoning can range from very sever to not very, depending on what bacteria or virus is the cause. Salmonella is the name for a common group of bacteria. The bacteria can effect different people in different ways. It can cause a serious sickness in older adults, infants, and persons with chronic diseases. Cooking and pasteurization can kill Salmonella. Two caused by this bacterium are the lettuce recall from major supermarkets and the mayonnaise contamination on Melbourne Cup Day, by Piccalilli Catering.
Typhoid fever is caused by the bacterium Salmonella typhi, a member of the genus Salmonella, which is included in the Enterobacteriaceae family. Salmonella typhi cells are aerobic, gram negative rods that
What they found was a Salmonella Typhimurium infection, a type of bacteria that can cause many illnesses in both animals and humans. It is most commonly known as Salmonella the food-borne illness you get from eating contaminated food leading to food poisoning. There are three types of Salmonella, two of which are more severe than the one researchers found on the Egret bird. The two are called Non-Typhoid Salmonella which are Salmonella Javiana and Salmonella Enteritidis, non-typhoid can cause gastroenteritis which is inflammation of the stomach and intestines, and bacteremia which is the presence of bacteria found in the blood. The third type of Salmonella is called Typhoidal Salmonella which can cause typhoid fever and is caused by the bacteria Salmonella Typhi which is the one the researchers found on the dead Egret found by the
Salmonella is a prokaryotic, rod shaped, bacterial organism. It is nonsporeforming and Gram-negative.(1) Salmonella is responsible for almost 60 percent of reported cases of bacterial food borne illness and 40 percent of all food borne illness of any kind. Salmonella survives digestion and reproduces in the small intestine, making people sick. Salmonella has hundreds of different types, all of which cause much the same illness in humans. Eating food containing live salmonella bacteria causes salmonellosis. (2)
