Salmonella—Prevalence and Prevention Strategies
Background/History
Salmonella is a bacteria commonly found in the intestinal tracts of humans and animals, including reptiles, farm animals, and rodents. In 1885, Dr. Theobald Smith, a Department of Agriculture researcher investigating hog cholera, is the first to identify Salmonella enterica, formerly called Salmonella choleraesui. Dr. Smith worked under Dr. Daniel E. Salmon, who became the bacteria’s namesake.1
There are around 2,500 different serotypes of Salmonella bacteria. Salmonella can be grouped into typhoidal (S. Typhi and S. Paratyphi) and non-typhoidal (including Typhimurium and Enteritidis, the most common serotypes in the United States.2
In the early 20th century, Irish immigrant Mary Mallon was identified as the first asymptomatic carrier of typhoid. Now an infamous public health case study, “Typhoid Mary” infected an estimated 51 people with typhoid fever over the course of her career before being forcibly quarantined by state public health officials. In spring 1985, 168,000 to 197,000 people were sickened with salmonellosis in northern Illinois, comprising the largest outbreak of Salmonella food poisoning in United States history. Investigators determined the cause to be Salmonella typhimurium strain of bacteria associated with the Hillfarm Dairy in Melrose Park, Illinois. 3 Salmonella has also been used as a tool of bioterrorism. In 1984, 751 individuals were deliberately poisoned by salad bars at 10 Oregon restaurants. Followers of Indian mystic guru Bhagwan Shree Rajneesh hoped to incapacitate the voting population of the city so that their own candidates would win the 1984 Wasco County elections. 4
Prevalence
Salmonella causes salmonellosis, one of the most common foodborne illnesses in the world. The WHO estimates that tens of millions of people contract salmonellosis each year, resulting in around 100,000 fatalities. In the US, around 42,000 cases are reported per year, representing an estimated 1.4 million total cases and around 400 deaths.5 Cases are likely underreported as salmonellosis can result in relatively mild illness in healthy adults. Young children, the elderly and the immunocompromised are the most likely to have severe infections.6
Salmonella Typhi causes typhoid fever, which is largely obsolete in the United States (due to widespread vaccination), but still results in an estimated 12-33 million cases and 600,000 deaths per year in developing countries.7 As of 2000, more than 90% of the morbidity and mortality associated with typhoid fever occurred in Asia, including Pakistan, India, Vietnam, China, and Indonesia.8 The CDC advises travelers to this region be vaccinated.
Mechanism of Toxicity
Pathogenesis
Salmonella are usually associated with hosts, but have been found to be able to survive on surfaces for weeks. In most cases, Salmonella bacteria are ingested through food or water contaminated with human or animal excreta. Organisms travel to the distal small bowel, where microphages ingest the organism and spread it to the lymph nodes, spleen, and liver.9

Figure 1
Distinct from many other bacteria that can produce toxins, Salmonella itself is toxic. A lipopolysaccharide in Salmonella triggers an allergic reaction, but the symptoms experienced are the body’s reaction to the resulting infection. Figure 1 illustrates Salmonella bacteria being ingested by microphages as well as direct invasion of the epithelial cells, leading to inflammation and local/systemic dissemination in the intestine and other organs.

Clinical presentation
Infections from Salmonella usually produce one of three distinct illnesses: nontyphoidal enterocolitis, nontyphoidal focal disease, or typhoid (enteric) fever. Enterocolitis from non-typhiodal Salmonella strains usually results in loose and bloodless stool for 6-72 hours, but can result in large-volume, cholera-like diarrhea for 3 to 7 days in severe cases. 48-hour fever, abdominal cramps, chills, and heachache are common for nontyphoidal enterocolitis.10 The second manifestation, nontyphoidal focal disease, can occur with or without the presence of bacteremia (Salmonella bacteria in the blood).It results in pain in the affected organ, commonly the GI tract, endothelial surfaces like heart valves, lungs, joints, bones, or soft tissue. Organs compromised by preexisting conditions are particularly susceptible.10
Infection from typhoid and paratyphoid strains cause up to four weeks of fever, rash, fatigue, dry cough and headache, and sometimes diarrhea and vomiting. Between 10 and 15% of patients develop the most severe form of the disease, which results in multisystem toxemia. After 2-3 weeks of these symptoms, more grave complications may occur, including intestinal hemorrhage or perforation.11
Exposure Level and Risk Assessment
Exposure Levels
Salmonella bacteria are commonly found in raw poultry and eggs, but can also be present in raw meat, unpasteurized dairy, and raw vegetables and fruit. They can also be spread through contact with human feces. Additionally, household pets such as cats and particularly birds and reptiles can be Salmonella carriers. 12
In a study of 11 salmonellosis outbreaks in the United States, the actual doses required for infection were calculated to be <103 organisms in six cases; the outbreaks with higher doses involved very high rates of attack and short periods of incubation. 13 A 2001 study of dose-response relationship in rats, illness was only observed in animals exposed to doses of 10(8) cfu or more. At lower doses, changes in the gastrointestinal tract were observed, but did not result in full-blown salmonellosis.14 Assuming children under 5 years of age represented a more susceptible population, it was estimated that at the doses observed in Salmonella outbreaks (approximately 2 and 4 log CFU/g), the susceptible population was 1.8 to 2.3 times more likely to get ill.15
An infected person can carry Salmonella bacteria for days or even months, even while asymptomatic. People treated with oral antibiotics and children tend to carry the bacteria longer, presenting significant risks for schools and daycares.16
Risk Assessment
Study conducted in 1990 following severe Salmonella Enteritidis outbreak linked to contaminated eggs in the US found that less than 1 in 1000 eggs from “infected” flocks are contaminated. An infected hen laid one contaminated egg in every 200, resulting in an endemic level of 1 in 10,000 to 14,000 eggs produced. For healthy adults who eat fully cooked eggs, risk for illness is one in every 1.6 million eggs consumed. Risk is stated to be higher for the immunosuppressed and for those who consume raw or partially cooked eggs.14
As salmonellosis is one of the most common foodborne illnesses, there are ample toolkits for determining Salmonella risk, especially in relation to poultry. The objective is to reduce “farm-to-table” transmission. USDA offers an Egg Production module to determine quantitative microbial risk assessment for SE in shell eggs and egg products, illustrated below.17

Source: USDA/FSIS Shell Eggs Processing and Distribution Module
Standard USDA recommendations for liquid whole eggs are pasteurization at 60 degrees Celsius for 3.5 minutes. The following figure uses linear regression to illustrate the reduction in Salmonella Enteritidis infections following pasteurization at varying temperatures.

Risk for typhoid or paratyphoid fever is very low in the US due to vaccination, and the risk of typhoid fever is highest for travelers to southern Asia (6–30 times higher than for all other destinations).18 Generally, more bacteria are required for the development of typhoid vs paratyphoid fever. In Southeast Asia, urbanization has increased the risk of typhoid and paratyphoid fevers. In a study conducted in Jakarta, Indonesia, consuming food from street vendors was found to be associated increased odds of paratyphoid fever (Odds Ratio 3.34), as well as recent flooding in the community (Odds Ratio 4.52). Independent risk factors for typhoid included no use of soap for handwashing (Odds Ratio 1.91), sharing food from the same plate (Odds Ratio 1.93), and no toilet in the household (Odds Ratio 2.20).19
Preventing/Controlling Exposure
Controlling at the Source and Along the Path
In recent years, the USDA has developed stricter standards for poultry processing units in response to rising salmonellosis outbreaks. In 2015, the USDA’s Food Safety and Inspection Service passed new pathogen reduction standards for chicken parts, ground chicken, and ground turkey, aimed at achieving a 30 percent reduction in illnesses from Salmonella.20 Standards for ground products will be more stringent than those for whole poultry products, as the risk of Salmonella contamination increases with processing. As of 2010, eggs from commercial flocks that are known to be infected are pasteurized instead of being sold as grade A shell eggs. The rule also includes refrigeration requirements during storage and transportation. 21 Additionally, state agencies and authorized laboratories of the USDA certify participating breeding flocks and hatcheries of chickens that lay eggs as SE clean (“tested free”). (CDC, 2010)
Following Salmonella outbreaks linked to peanut butter in 2009, 2012, and 2014, new techniques were developed to sanitize machinery following contamination that have been proven effective. In laboratory experiments, no Salmonella was detected in environmental samples on XLD (<0.16 log CFU/cm2) following application of the hot oil and 60% isopropanol sanitation solution (±quaternary ammonium compounds). 22
Controlling at the individual level
Standard recommendations for avoiding Salmonella contamination include storing poultry, meats, and eggs at ≤40° F (≤4° C), discarding cracked eggs, thoroughly cooking poultry and eggs, choosing pasteurized eggs and dairy products, and washing produce before consumption.23 The incidence of Salmonella contamination changed from 30% at retail to 0.16% after cooking to 4% at consumption. 24
CDC recommendations include thorough handwashing after handing raw meat and poultry. Kitchen utensils, countertops, and cutting boards that have come in contact with raw meat and poultry should be washed with warm, soapy water to reduce the risk of cross contamination. Handwashing procedures should be used following contact with household pets such as reptiles or birds or their excrement. The CDC recommends that the elderly, immunocompromised, and small children and infants avoid direct contact with these sorts of household pets as their risk of severe Salmonella infection is greater.23
Summary
Salmonella constitutes a major public health risk in the United States and abroad. Infections from non-typhi Salmonella have increased 10% in recent years.25 Typhoid has largely been eliminated through vaccination in the United States, but remains a major source of illness and mortality in developing countries. Along with following standard recommendations for handling raw meat and poultry, closer monitoring of industrial food processing and increased internal controls could help prevent large-scale infection. However, published studies have not ascertained a strong link between free-range and organic practices and lower Salmonella incidence (versus traditional commercial practices). 26 Future research should concentrate on best management practices for poultry production, economical and effective sanitation methods for food processing equipment, and public education for restaurant workers and households on the importance of thorough cooking and timely refrigeration. Widespread typhoid vaccination should be emphasized for Asian nations.

Salmonella

...infectious disease? Salmonella germs have been causing illnesses for over a hundred years. It was discovered by Dr. Daniel E. Salmon in 1885. Salmonella is a infectious rod shaped, gram negative bacteria that can cause diarrhea illnesses in both humans and animals. Salmonellosis is an infection that is caused by the presence of salmonella bacterium in the small intestine. Salmonella can cause other diseases such as typhoid fever and paratyphoid fever. The salmonella family has over 2,300 serotypes of bacteria, with Salmonella Enteritidis and Salmonella Typhimurium being the most common strains of the pathogen in the United States. Strains of salmonella that have no symptoms for animals can make people sick, and vice versa. If the bacteria is in your food there is usually no way for one to taste, smell, or even see the pathogen in your food. 2. How is this infectious disease transmitted through food or water? Salmonella infections in humans are normally caused by infected foods such as beef, poultry, and eggs that have not been cooked or stored properly. This has a lot to do with poor kitchen and personal hygiene. Polluted water, contact with feces from an infected person, or contact with reptiles such as snakes and turtles are other sources for salmonella infection. Most salmonella bacteria is destroyed by the stomach acids, but if there is a high concentration in infected foods then some can manage to survive and multiply. Salmonella can survive for several...

A fun fact about Salmonellosis is where it got its name. The name derived from the scientist who discovered it whose name was Salmon. There are many different types of Salmonella bacteria. There are two of the bacteria that are most prominent. These bacteria are Salmonella serotype Typhimurium and Salmonella serotype Enteritidis. When infected, the person develops diarrhea, fever and abdominal cramps at least twelve to seventy-two hours after infection. The duration of the infection can take anywhere from four days to a week in order to subside. There are definitely some consequences of Salmonella. Even though the symptom of diarrhea may be gone, it can take months for bowel habits to regulate to normal. Infected people may also develop pain in their joints, eye irritation, and pain when urinating. These symptoms are called reactive arthritis. It can last for months or even years, unfortunately, it can also lead to chronic arthritis. Most people do not need to be treated for Salmonellosis but if diarrhea persists and becomes severe, IV fluids may have to be administered. If the bacteria travels from the intestines to the bloodstream, antibiotics (ampicillin) will be administered by a doctor. The Salmonella bacteria can be transmitted through food like raw poultry, beef, unwashed fruit, and eggs. It can also be transmitted...

Salmonella bacteria are capsule shaped that are known to cause diseases in humans, animals, and birds, especially poultry. Many of these bacteria can cause illness in humans, and they can pass from the feces of people or animals to through the foods processing or harvesting. Humans usually contract salmonella from contaminated food; it is most common among poultry but can taint almost any food type. Some outbreaks have included the bacteria found in raw eggs, raw meat (ground beef and other poorly cooked meats), egg products, fresh vegetables, nuts, and contaminated water. Salmonella can enter water in a bowel movement of an infected human or animal through sewage overflows, sewage systems that are not working properly, or wells after severe flooding. Infected milk is another possibility of infection, but pasteurization usually destroys the germ. A recent major outbreak in July of 2012 by Cargill meat solutions Corporation was found in over 29,000 pounds of fresh ground beef products. A total of 46 people in 9 states were reported to have contracted the virus, thankfully no deaths were reported.

...Food-Borne Illness: Salmonella 1. What is the infectious agent that causes this infectious disease? For example, name of the bacteria, virus, or parasite. Salmonella is a bacterial infection of the intestines. It is also known as Salmonellosis. This bacterium is a shaped like a rod and takes on a reddish color. There are over 2,300 types of bacteria that make up the salmonella family. The bacterium that is the most common is Salmonella Enteritidis and Salmonella Typhimurium. Those types of bacteria are cause for over half of all cases of Salmonella. 2. How is this infectious agent transmitted through food or water? Salmonella is transmitted through food and water that has been in contact with feces. The most common ways salmonella is transmitted is through fruits, vegetables, undercooked meat, poultry and seafood. This happens though the process of harvesting food in unclean areas or in contaminated water. Other ways that Salmonella has been transmitted is through reptiles and amphibians because they do not get sick from carrying salmonella in their guts; they spread Salmonella through their droppings in their cages. Undercooked eggs or products that use eggs can cause a person to get salmonella if the chicken who laid the egg was infected. The lack of proper hygiene is the main reason that Salmonella is spread throughout so many places. 3. What is an example of a real life outbreak of this foodbourne illness in the United States?

Salmonellosis is an infection with bacteria called Salmonella. The Salmonella consist of a range of very closely related bacteria, many of which cause disease in humans and animals. There are many different kinds of these bacteria. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common types in the United States. Salmonella infection is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in animal and human intestines and are shed through feces. Humans become infected more frequently through contaminated water or food. How is this infectious agent transmitted through food or water? Salmonella is transmitted through food or water during food/water processing or food/water handling. Not separating cooked foods from ready-to-eat foods. Using utensils on cooked foods that were previously used on raw foods and placing cooked foods on plates where raw foods once were while haven’t been cleaned thoroughly. Eating high-risk foods like raw or lightly cooked eggs, undercooked ground beef or poultry, and unpasteurized milk makes it easy to transmit salmonella.

Salmonella is a motile, non-spore-forming, gram-negative, rod- shaped bacterium in the family Enterobacteriaceae and the tribe Salmonellae. The genus Salmonella is divided into two species - S. enterica and S. bongori; both of which are pathogenic to humans. However, S. enterica is a greater public health concern and is further divided into 6 subspecies which are then further subdivided into serotypes. Epidemiology and Clinical Significance Depending upon the serotype, Salmonella can cause two types of illness (1) nontyphoidal salmonellosis and (2) typhoid fever. 2 How is this infectious agent transmitted through food or water? Salmonella bacteria can be found in food products such as raw poultry, eggs, and beef, and sometimes on unwashed fruit. Food prepared on surfaces that previously were in contact with raw meat or meat products can, in turn, become contaminated with the bacteria. This is called cross-contamination. Salmonella bacteria are taken in by mouth and it may occur by inadequate cooking, cross contamination or person to person spread. 3What is an example of a real life outbreak of this foodborne illness in the United States?

Bacterial Infection: Salmonella

...Salmonella is a bacterial infection cause by gram negative bacteria salmonella. Since bacterica can evolve there are two main kinds of the Salmonella bacteria. Two specie are cause by typhoid fever, Salmonella typhi and Salmonella paratyphi. Salmonella typhi only affects people and Salmonella paratyphi reside in people but sometimes in wild animals. People are usually become infected when they eat contaminated food, examples are uncooked poultry or eggs. The bacteria usually infect the digestive tract but can travel through the bloodstream and infect other parts of the body Symptoms are nausea, cramps, abdominal pain, watery diarrhea, fever, and vomiting. It can also attack the liver and spleen which causes them to swell. To see if you are infected with this bacteria they take a portion of stool and test it. Salmonella bacteria also causes several types of infection. Most often, these bacteria cause gastroenteritis, but they sometimes cause typhoid fever, a more serious infection. When the intestine is attack, symptoms usually start to show around 12 to 48 hours after the bacteria are ingested. Then nausea and abdominal pain occur, soon followed by watery diarrhea, fever, and vomiting. Salmonella symptoms tend to clear up in about 1 to 4 days. Uncommonly things could gradually get worse and symptoms are more severe and last a long time. However, approximately 40,000 cases of salmonellosis are reported in the United States.

Chronic Food Borne Illness Salmonella

...Illness Salmonella SCI/163 Troy Bushman November 18, 2013 1 The infectious agent pathogen that causes salmonella is called salmonella enteritis. The bacteria are larger than a virus; but, are visible to the eye with the microscope. It is rod-shaped, gram negative, non-motile bacteria that do not form spores. Interestingly enough it communicates to its fellow bacteria via AHL. It infects the cell, multiplies within it; and then, bursts the cell. Special effector protein factors are required for salmonella intestinal invasion and the induction of fluid secretion and for inflammatory responses. There are about six names species names of it, salmonella enteritis’s, and salmonella enteric which cause the human disease. “Salmonella is one of the most commonly reported types of food-borne illness. Salmonella is caused by a variety of different bacteria. The ensuing illness is treatable, but in some cases, fatal. Most of the time people aren’t even aware they have salmonella, they think something they ate didn’t agree with them and the symptoms are mild and disappear quickly. I believe no one really takes any action of going to a hospital or to their doctor until the symptoms worsen and become unbearable or scary for them that’s at least what I do, which I shouldn’t because instead of me finding out what problem was solving it quickly, I go through the pain and agony until I can’t take it anymore.

Increase exposure are International travel where developing countries with poor sanitation. Owning a pet bird or reptile is also a risk factor if they are infected with salmonella bacteria. Stomach has a natural defense against salmonella. Some disorders are antacids, inflammatory bowel disease and recent use of antibiotics can shorten the natural defense. Most people are infected with salmonella by eating foods that are contaminated by feces. The most infected foods are raw meat, poultry, and seafood. When the meat is raw it becomes contaminated in the process of distribution. Seafood is contaminated when the water they are harvest is contaminated. Eggs can be contaminated from infected chicken making the eggs bad before it is form. Fruits and vegetables, mostly imported ones can become contaminated by washing in contaminated water. This mainly occurs when juices from raw meat comes in contact with uncooked foods like salads. The 2008 United States salmonellosis outbreak began in the spring of 2008 when hundreds of people throughout the United States fell ill after consuming contaminated food.

Salmonella

...Salmonella is a type of bacterial found in the intestinal track of humans and other animals. Humans can contract salmonellosis when they eat food contaminated with animal feces, normally though as food poisoning. The meat, poultry, milk and cheese are common sources, but you can get salmonellosis with any food, including vegetables. Transmission can occur if you are infected and do not wash your hands after going to the bathroom then the bacteria can be passed through the food you are preparing, also if you use the same knife to cut raw chicken then cut tomatoes or other vegetables and do not wash it between using it again, therefore it will contaminate the other dishes with the bacteria. The bacteria is killed in the cooking of food, but if a carrier of the infection does not wash their hands after using the bathroom, any food that he or she touches is contaminated. Symptoms of salmonellosis are diarrhea, fever and abdominal pain are common between 12 and 72 hours after the individual was infected and recovers from 4 to 7 days without treatment, but sometimes salmonella spreads from the intestines into the blood stream and other body regions. If salmonella spreads through the body, a person could even die unless they receive antibiotics. People with weakened immune systems, elderly, and infants are more susceptible to get severely ill. People with diarrhea usually recover completely, but your bowel movements may not return to normal for several months. In a small number...
