What Are Common Causes and Types of Foods That Can Trigger Food Poisoning?

Food-borne illness, sometimes referred to as food poisoning, can be brought on by eating contaminated, damaged, or poisonous food. Food poisoning frequently manifests as nausea, diarrhoea, and vomiting. Despite being quite uncomfortable, food poisoning regularly occurs.

Depending on where the contamination came from, it may take between 30 minutes and eight weeks for symptoms to start showing up. Most instances will end in a week, therapy, or no treatment.


There is a reasonable risk that food poisoning won't go unnoticed.

Depending on the infection's origin, symptoms might change.

Several of the symptoms associated are frequently present in cases of food poisoning −

  • Stomach aches

  • Diarrhea

  • Gastrointestinal discomfort

  • Appetite loss

  • Slight fever

  • Tiredness

  • Headaches

The following are signs of food poisoning that might be fatal −

  • Three or more days' duration of diarrhea.

  • A temperature of more than 102°f (38.9°c).

  • Having trouble talking or seeing.

  • Bad breath, generating minimal to no urination, and trouble retaining fluids are all signs of severe dehydration.

  • Urine with blood.

Consult a doctor or get emergency medical help if you develop one of the following conditions.

What Causes Food Poisoning?

Food poisoning has three main causes: bacterial infection, protozoa, or viral infection.

Bacteria − The most typical culprit behind food sickness is, by far, bacteria. Salmonella and E. coli are among the bacteria that first spring to mind when considering harmful microorganisms. Campylobacter and C. botulinum are other well-known but life-threatening bacteria that might be present in our meals.

Protozoa − Protozoan-related food poisoning is less frequent than bacterial-related food poisoning, although both pathogens are exceedingly deadly. Your digestive tract can harbor these parasites that can go unnoticed for years. If some parasites establish a home in a person's intestines, they may cause more severe adverse effects, especially in immune-compromised individuals and pregnant women.

Virus − A virus that rarely results in fatalities can also induce food poisoning. Similar symptoms are caused by other viruses, although they don't happen as frequently.

Additionally, food can act as a vehicle for the hepatitis A virus, which causes liver disease.

These viruses are present in almost all of the food that people ingest. However, heat from cooking often kills microbes on the food before it reaches our plate. Food poisoning is commonly brought on by raw foods since they haven't been prepared.

Occasionally, germs from faeces or vomit may come into contact with food. This happens most frequently when a sick person prepares food without first washing their hands.

Often contaminated foods include dairy, meat, and eggs. Viruses and other disease-causing organisms can pollute water.

Food-Borne Illness Remedies

Most food poisoning cases may be handled at home. The following are some methods for treating food poisoning −

Be Hydrated

Drinking enough water is essential if you're suffering from food poisoning. Electrolyte-rich sports beverages can be beneficial. Fruits, juices, and coconut water may aid with tiredness and carbohydrate restoration.

Steer clear of coffee, which can aggravate the digestive system. An upset stomach may be soothed by decaffeinated teas infused with calming herbs, including chamomile and peppermint.

Take Over-The-Counter (OTC) Drugs

You can control diarrhea and reduce nausea by using over-the-counter (OTC) drugs such as loperamide and Pepto-Bismol. Before using these treatments, you should consult a doctor, as the body naturally eliminates toxins from the body through vomiting and diarrhea. Furthermore, using these drugs may make your condition appear worse than it is and postpone your search for medical help.

  • Note − Getting lots of sleep is crucial for those with food illnesses.

  • If you have a serious case- You could need hospitalized intravenous (IV) hydration if your food poisoning is severe.

  • While you recover, a lengthier hospitalization may be necessary for the most severe types of food poisoning. Rarely individuals with severe C. botulinum infections could even need mechanical breathing.

What To Eat?

It's preferable to progressively delay eating solid foods until after vomiting and diarrhea have stopped. Instead, gradually return to your usual diet by consuming bland, easy-to-digest foods and low-fat beverages like −

  • Sea salt crackers

  • Toast

  • Bananas

  • Oatmeal

  • Blend potatoes with rice

  • Veggie soup

  • Juices diluted

  • Chicken broth

  • Drinks with no caffeine

Even if you feel better, refrain from eating the following meals that take longer to digest to keep your gut from becoming more uncomfortable −

  • dairy items, particularly milk and cheese

  • foods high in fat

  • foods that have been fried

  • meals with a lot of seasoning

  • meals rich in sugar, spicy foods

Additionally, Avoid

  • caffeine

  • alcohol

  • nicotine

Common Foods that Cause Infection

Food-borne infections and poisoning are more frequently linked to some foods than others. If the food is tainted, it may carry dangerous bacteria, rendering people quite ill.

  • Raw or barely cooked meat and poultry, raw or overcooked pasta, raw eggs, unpasteurized milk, and raw shellfish are the raw animal items that are most likely to be contaminated.

  • Vegetables and fruits can also become infected.

  • Even while some foods are more likely to make you sick than others, all foods can become contaminated on the farm, during preparation, or at other points along the food supply chain, as well as through cross-contamination with meat in kitchens.

  • Turkey, Chicken, Beef, and Pork – You risk illness if you consume raw or undercooked meat or poultry. Campylobacter may be found in most uncooked poultry. It might potentially be contaminated with pathogens like Clostridium perfringens and Salmonella. Bacteria, including Yersinia, Salmonella, and E. coli, might be present in raw meat.

  • Fruits and Vegetables - Fresh produce has many health advantages, but occasionally eating raw fruits and vegetables might put you at risk for food poisoning due to dangerous bacteria, including Salmonella, E. coli, and Listeria. Cross-contamination in the kitchen is one way fresh fruits and vegetables can get infected while traveling from the field to the table.

  • Milk products - The consumption of soft cheeses, ice cream, yogurt, and other dairy products made with raw (unpasteurized) milk might make you quite ill. Due to the possibility of dangerous bacteria in raw milk.

  • Eggs - Even though the egg seems clean and uncracked, it might still contain the Salmonella bacterium, which can get you sick. When cooking dishes that need raw or undercooked eggs, use pasteurized eggs and egg products.

  • Seafood - Avoid eating undercooked or raw seafood, including crabs, fish, and foods like ceviche, certain sushi, and sashimi, to prevent food-borne illness.

  • Sprouts and flour - Germs thrive in the warm, moist conditions required to develop sprouts. Food poisoning can result from eating raw or barely cooked sprouts, including alfalfa, beans, and other kinds. As a whole, flour is an untreated, uncooked agricultural product. When grain is still on the farm or during other flour-making processes, it can get contaminated with harmful microorganisms. Food created with flour is cooked, killing any bacteria. It would help if you never ate uncooked dough or batter because of this.


The chance of food poisoning being fatal is quite unlikely. The good thing is that most individuals fully recover from food poisoning within only a few nights, with or without treatment, even though it is a very painful condition.
