Everything You Need to Know About Food Poisoning


Food Poisoning: Food poisoning is an illness caused by eating food that contains harmful microorganisms or other contaminants. These microorganisms can include bacteria, viruses, and parasites, which can lead to symptoms such as stomach cramps, nausea, vomiting, diarrhea, and fever. In severe cases, food poisoning can also lead to hospitalization and death.

In India, food poisoning is a common health problem and it causes significant morbidity and mortality. The rate of death due to food poisoning in India is not well reported but according to the National Centre for Disease Control (NCDC) in India, Food poisoning is responsible for a significant number of hospitalizations and deaths each year.  

The exact number of deaths is not well reported because many cases are not reported or are not recognized as food poisoning.

However, it is important to note that with increasing awareness and proper food safety regulations in place, the number of cases and deaths due to food poisoning has gone down. But still, it is quite common in rural and semi-urban areas where food safety and hygiene are not given much importance.

What Leads to Food Getting Contaminated?

There are a variety of factors that can contribute to food poisoning. 

Some of the most common include:

  • Contamination during food production or processing: Foods can become contaminated at any point during the food production and processing chain, including during growing, harvesting, transportation, storage, and preparation.
  • Poor sanitation: Foods can become contaminated if they come into contact with dirty surfaces, equipment, or water. This can occur during food production, processing, or preparation, or if the food is stored or served in unsanitary conditions.
  • Improper storage and handling: Foods can become contaminated if they are not stored or handled properly. This includes not storing foods at the appropriate temperature, not keeping raw and cooked foods separate, or not properly washing or sanitizing food preparation surfaces and equipment.
  • Cross-contamination: Foods can become contaminated if they come into contact with other foods that contain harmful microorganisms, either directly or through contact with cutting boards, utensils, or other kitchen equipment.
  • Undercooked or raw food: Foods that are undercooked or consumed raw can contain harmful microorganisms that can cause food poisoning.
  • Natural toxins: Certain foods can contain naturally occurring toxins that can cause food poisoning if consumed in large enough amounts.
  • Personal hygiene: Poor personal hygiene of food handlers also leads to food contamination

It is important to note that in India, the lack of proper regulations and lack of enforcement of food safety regulations also leads to a significant number of food poisoning incidents.


What are The Symptoms of Food Poisoning?

The symptoms of food poisoning can vary depending on the type of food that was consumed, the type of microorganism or contaminant that caused the illness, and the individual’s own immune system. However, some common symptoms of food poisoning include:

  • Nausea: A feeling of discomfort in the stomach that can lead to vomiting.
  • Vomiting: The act of forcefully expelling the contents of the stomach through the mouth.
  • Diarrhea: Loose, watery stools that occur more frequently than normal.
  • Stomach cramps: A feeling of tightness or discomfort in the stomach.
  • Abdominal pain: Pain or discomfort in the stomach area.
  • Loss of appetite
  • Fatigue
  • Headaches
  • Low-grade fever

Symptoms typically appear within a few hours to a few days after eating contaminated food and can last for several days, most of the time it goes away within a week.

However, in some cases, symptoms can last longer, and in severe cases, food poisoning can lead to hospitalization and even death.

It’s important to seek medical attention if you have severe symptoms, such as persistent vomiting, severe abdominal pain, high fever, blood in your stool, or symptoms that last more than a week.

How to Treat Food Poisoning?

Treatment for food poisoning depends on the severity of the symptoms and the cause of the illness. In most cases, food poisoning can be treated at home with self-care measures such as:

  • Hydration: Drink plenty of fluids to replace fluids lost due to vomiting and diarrhea, such as water, clear broths, frozen water or ice pops, and clear soda (Sports drinks should be avoided as they contain high levels of sugar which can further dehydrate the body)
  • Rest: Get plenty of rest to help your body recover from the ill ness.
  • Over-the-counter medications: Take over-the-counter medications, such as acetaminophen or ibuprofen, to relieve pain and fever, but avoid anti-diarrheal medication unless it is prescribed by a doctor.
  • Avoid solid foods: Wait until nausea subsides before attempting to eat solid foods, then start with a small amount of easily digestible food such as a BRAT diet (Bananas, Rice, Applesauce, Toast)

It is important to note that certain food poisoning cases caused by bacteria, such as Salmonella or E. coli, can require antibiotics to fully recover. 

A Doctor should be consulted if symptoms persist, are severe, or if you have underlying health conditions.

Prevention is the best method of treatment and that can be done by following safe food handling, storage, and preparation techniques, and by cooking food to appropriate temperatures to kill harmful microorganisms, also taking care of personal hygiene, proper sanitation and regular cleaning of kitchen and food preparation areas are an important preventative measure against food poisoning.

Guidelines to Prevent Food Poisoning

To prevent food poisoning, it’s important to practice safe food handling, storage, and preparation techniques. Some ways to do this include:

  • Cleaning: Wash your hands and all food preparation surfaces with soap and hot water before and after handling food.
  • Cooking: Cook foods to appropriate temperatures to kill harmful microorganisms. Use a food thermometer to check the internal temperature of meats, poultry, and seafood.
  • Separating: Keep raw and cooked foods separate to prevent cross-contamination.
  • Chilling: Refrigerate or freeze perishable foods promptly to slow the growth of harmful microorganisms.
  • Personal hygiene: People handling food should maintain good personal hygiene, they should regularly wash their hands, cover their hair, wear clean clothes, and should not work if they are unwell.
  • Food sourcing: Be mindful of where and how the food is sourced, buy food from reputable sellers, and avoid purchasing food from street vendors or those who don’t follow proper food safety regulations.
  • Educating yourself: Learn about the signs and symptoms of food poisoning and what to do if you suspect that you or someone you know has been affected by food poisoning.

By following these guidelines and regulations, you can reduce your risk of food poisoning and help ensure that the food you eat is safe and healthy.
