Salmonella Symptoms
Salmonella Symptoms
Salmonella symptoms may range from an upset stomach to a fever, and are often mistaken for some other kind of ailment. The genus of the salmonella bacterium has over 2500 species, which can become parasites in human bodies, birds, and other animals. Salmonellosis is the condition wherein the body experiences the kind of poisoning after accidentally ingesting salmonella.
Salmonella poisoning has become very common, and in the United States, it is estimated that there are around 40,000 cases annually, with 1.25% of the cases leading to death. This condition is also common even in children under four years of age, with around 15,000 cases reported annually. With this, it is important to know how the condition can be prevented and cured to ensure everyone’s well-being.
Causes of Salmonella Poisoning
People who have a weak immune system might immediately exhibit salmonella symptoms right after eating food that is contaminated with the a small amount of the bacteria. On the other hand, if a person has a strong immune system, he might not suffer from the condition unless he happens to ingest an extremely large amount of the bacteria. This means that boosting a person’s immune system can be a good way to prevent food poisoning by salmonella. If left untreated, the symptoms of salmonella can aggravate further and turn into more severe complications like bacteremia, gastroenteritis or typhoid fever.
Primarily, salmonella food poisoning is caused by unsanitary practices and improper handling of food. Poor hygiene is the most common cause of food poisoning because a dirty environment can cause the food to get contaminated with salmonella and other parasites that could damage the body.
As the salmonella bacteria are parasites in the body, it takes about 6-72 hours to incubate before beginning to affect the normal functions of the human body. After such incubation period, salmonella symptoms will then surface and could last between 4-7 days. Fortunately for some, the effects of salmonella poisoning could subside even without taking any medication, and the parasite would naturally be flushed out of their systems. Note, however, that as the salmonella is flushed out through the human feces, it does not mean that the parasite will no longer be in a person’s system.
People who have exhibited salmonella symptoms could still be carriers of the bacteria even if the obvious symptoms are already gone. The bacteria could remain dormant inside the body, get out through feces and possibly get in contact with food that is prepared in an unhygienic manner. If this is the case, then it is very possible that the salmonella bacteria could still be considered contagious.
Even animals that are carriers of salmonella can cause salmonella food poisoning, as in the case of eggs that are not properly cooked. Additionally, meat products that are eaten raw or served rare could still have salmonella in them, which, when ingested, can infect the consumer. Vegetables that have not been washed thoroughly or cooked properly might also have salmonella, and once eaten, can induce the salmonella symptoms in human beings. Nuts, cereals, and even water can be contaminated with salmonella, thus making it essential for a person to watch the foods he or she eats.
Salmonella Symptoms
Humans might experience the following symptoms if they contract salmonella.
- Loss of appetite, weakness, nausea, vomiting, and diarrhea are among the most common salmonella symptoms that can be noticed immediately. In some cases, blood can be seen in the feces.
- Muscle pains, headaches, and inexplicable fatigue.
- Moderate chills and fevers, and dizziness.
- Swollen intestines, stomach, and other parts of the digestive system. These are often accompanied by abdominal cramps caused by gastroenteritis, which results from untreated salmonellosis.
- Enteric fever and typhoid fever that is caused by salmonella can be experienced, and the symptoms include fevers that go up to 104°F, fatigue, mental instability, cough, and excessive sweating. Other symptoms like inflammation of the organs of the digestive system, and slow heartbeat can also be experienced.
- If salmonella is found in the bloodstream, this means that the condition has already elevated to bacteremia. The symptoms of this condition include rapid breathing and abnormal pulse rate, chills, and high fevers.
Avoiding the consumption of uncooked or rarely cooked meat and food that is prepared in an unsanitary manner would be a good place to start for the prevention of salmonella. If you are already experiencing severe salmonella symptoms, the bacteria may have already contaminated other parts of your body through your bloodstream, and you will need to see a doctor for antibiotics. In any case, salmonella symptoms can be prevented if a person pays close attention to his hygiene and the cleanliness of his surroundings.

Is Salmonella Contagious?
Is salmonella contagious? – Studies show that salmonella can be transmitted from one person to another due to the fact that this particular bacterium lives in both humans and animals. It naturally lives inside the host’s intestinal tract. Once an animal or a human defecates, the bacteria latches itself onto the fecal matter and waits for an opportunity to get in contact with various foods like vegetables and meat. When these foods are ingested, the salmonella has an opportunity to spread to a new host. So yes, salmonella is indeed contagious.
Modes of transmission
Almost all types of food can be a medium for salmonella bacteria. For as long as the food ingested is contaminated, the bacteria can be transmitted. The most common types of food normally contaminated with salmonella are raw beef, eggs, poultry, and milk. But some unlikely foods also get contaminated like fruits and vegetables.
Pets can also be a medium for salmonella. Particularly, reptiles such as snakes, turtles, and lizards are known to sometimes carry salmonella. When pets are infected with salmonella, if their fecal matter gets into contact with their owner, and the owner eats without properly washing his/her hands, it is highly likely that the salmonella bacteria will have been transmitted.
Is salmonella contagious just by touching someone who has it? – Apparently, the bacteria can only be transferred via the fecal-oral route. Although salmonella can be transmitted from one person to another, the person must first ingest the bacteria to acquire it. This is commonly the result of poor hygiene. When a person contaminated with salmonella uses the bathroom and does not properly wash his/her hands, salmonella can be transferred just by touching food items.
Treatment and Prevention
Studies have shown that people infected with salmonella can be treated with antibiotics. However, even though antibiotics are effective for salmonella treatment, the those who use antibiotics to treat their salmonella symptoms tend to be carriers of the bacteria for longer periods of time.
Some carriers of salmonella may ask, “Is salmonella contagious even if I remain dormant?” The answer is clear: salmonella, although dormant, can still be contagious. This is the reason why those working in kitchens or handling food items who are or have been infected with salmonella must receive prior written authorization from their regional health department before returning to work.
Some simple tips to prevent the transmission of salmonella include properly washing your hands before handling any food items and before eating, placing raw meats into separate bags to prevent them from dripping their juices onto other food items, and storing raw foods separately to prevent cross-contamination.
Kitchen utensils and cutting boards should also be thoroughly washed before and after preparing fish, poultry, and meat. Keep in mind to always wash the plate used to hold the raw meat before using it for anything else. Also, refrain from eating raw or half cooked meat or fish because there is a high risk of acquiring salmonella when the meat or fish is not thoroughly cooked.
Some mothers might ask, “Is salmonella contagious when eggs are consumed raw?” Since eggs can contain salmonella, the consumption of raw eggs even if mixed with salad dressings and sauces should be prevented.
Always remember to properly wash hands with soap and water after playing with pets, after cleaning the cat litter, and after using the bathroom. In addition to that, always wash fruits and vegetables under running water before consumption.
So is salmonella contagious? Regardless of how contagious salmonella is, when a person washes his/her hands after handling filthy things and prior to eating, the risk of getting salmonellosis and other diseases is close to zero.
