Understanding the Causes of Food Poisoning and What to Do About It

Preview image

It starts out innocent enough. You grab a quick bite from your favourite chaat stall or reheat last night’s curry. But hours later? Nausea hits. Your stomach twists, you’re dashing to the bathroom, and you’re left wondering: Was it something I ate? In India, food poisoning is far more common than most people admit—especially with changing weather, street food culture, and often casual kitchen hygiene.

So what really causes food poisoning? What bacteria is associated with food poisoning? And more importantly—what is good for food poisoning once it strikes? In this article, we’ll break it all down so you know what’s going wrong, how to fix it, and how to avoid it next time.

What is Food Poisoning?

Food poisoning happens when you eat food or drink water that has been contaminated with harmful bacteria, viruses, parasites, or toxins. Sounds scary? It can be. But it’s also usually preventable. The contamination can occur at any stage—from harvesting and processing to cooking and serving. Even storing food improperly can trigger bacterial growth.

In India, cases often spike during the monsoon due to the warm, moist conditions—perfect for bacteria to thrive. And let's be honest, sometimes we just ignore basic food safety habits. Unwashed vegetables, half-cooked chicken, or curd stored in the open? Yep, all risky.

Some of the most common culprits behind food poisoning in India include:

  • Street food exposed to dust and flies

  • Stale leftovers not properly refrigerated

  • Contaminated water, especially in rural or semi-urban areas

  • Raw meats handled on the same surface as vegetables

Why is it Called Food Poisoning?

Despite the dramatic name, it’s not always as lethal as the word “poisoning” suggests. The term simply refers to the body’s natural response to ingesting food that contains “bad stuff”—whether that’s bacteria like Salmonella or E. coli, or even harmful toxins created by microbes.

The symptoms—vomiting, diarrhoea, cramps—are your body’s way of saying, Get this out! Historically, doctors used “food poisoning” to describe any illness that occurred after eating spoiled or unsafe food. And while modern medicine now gives us specific names for different bugs and infections, the old term still sticks. It’s short, sharp, and accurate enough.

What is a Food Poisoning Answer?

If you’ve ever searched this phrase on Google, you’re not alone. People often want a quick, understandable explanation. So here’s your food poisoning answer:

Food poisoning is a short-term illness caused by consuming food or drinks contaminated with germs or toxins. It typically leads to stomach upset, vomiting, and diarrhoea, and may also include fever, cramps, or dehydration.

It can last anywhere from a few hours to several days, depending on the cause—and your overall health. Children, elderly people, and those with weak immune systems are usually hit harder.

What Causes Food Poisoning?

So, what is the main cause of food poisoning? In short—germs. But let’s break that down a bit.

The majority of food poisoning cases are caused by bacteria, viruses, parasites, or toxins that enter your food somewhere between the farm and your plate. In India, food safety can be a real challenge because of open-air markets, high humidity, irregular refrigeration, and, let’s be honest—our love for street snacks.

Common Bacteria Behind Food Poisoning in India

  1. Salmonella – Found in undercooked eggs, poultry, and milk. Causes high fever, cramps, and diarrhea.

  2. E. coli – Found in contaminated water, undercooked meat, and raw veggies. Can cause bloody diarrhea and stomach pain.

  3. Listeria – Found in unpasteurized dairy, deli meats, and refrigerated foods. More dangerous for pregnant women.

  4. Campylobacter – Found in poultry and untreated water. Triggers cramps and fever.

  5. Clostridium botulinum – Rare but severe. Linked to canned foods and improperly stored meals.

These germs thrive in warm, damp places—exactly what we get during the Indian monsoon and summer months. They also spread easily through poor kitchen hygiene, such as using the same cutting board for meat and vegetables. Some people don’t even reheat leftovers properly, which allows bacteria to grow overnight. Not good.

And it’s not just bacteria. Viruses like norovirus or rotavirus can also cause foodborne illness, especially in young children. Parasites like Giardia and Entamoeba also pop up, often in contaminated water.

Even toxins—like those from spoiled seafood or fungus on grains (like wheat or rice stored too long)—can lead to poisoning. It’s not always about germs. Sometimes, the food itself becomes toxic due to improper storage or cooking methods.

How to Know It’s Food Poisoning

Here’s a tricky part. A lot of people confuse food poisoning with regular indigestion, acidity, or even stomach flu. So, how do you know it’s food poisoning?

Symptoms Usually Start Fast

Unlike a virus that takes a while to kick in, food poisoning symptoms often show up within a few hours of eating. In some cases, it can take up to 24–48 hours, depending on the germ involved.

Common Symptoms Include:

  • Nausea and vomiting

  • Stomach cramps or pain

  • Loose motions or diarrhea (sometimes bloody)

  • Fever or chills

  • Dehydration (dry mouth, low urine, dizziness)

If you're experiencing three or more of these after a recent meal, there's a good chance it’s food poisoning.

But here’s the thing—most mild cases go away on their own in 1–3 days. However, if symptoms are severe or don’t improve, it’s time to see a doctor. Bloody stools, high fever, or signs of dehydration (like sunken eyes, dry lips, and little urine) shouldn’t be ignored—especially in children and older adults.

What is Good for Food Poisoning? Remedies and Treatments

Alright, so you think you’ve got food poisoning. What now? The good news is, most cases of food poisoning can be treated at home. The key is to stay hydrated and give your stomach a break while it heals.

Best Home Remedies in Indian Households

  1. ORS (Oral Rehydration Salts) – Easily available at any pharmacy, this helps replace lost fluids and electrolytes. A must for both kids and adults.

  2. Jeera (Cumin) Water – Known for easing digestion and reducing bloating. Boil a spoonful in water, cool it, and sip slowly.

  3. Lemon-Ginger Tea – Helps soothe nausea and fights infection. Add honey if needed, but avoid milk.

  4. Bananas and Rice (khichdi) – Easy on the stomach and helps bind loose motions.

  5. Curd (Dahi) – A probiotic that helps restore gut bacteria. Just make sure it's fresh and plain—not sweetened.

One old-school trick many grandmothers swear by? Saunf (fennel seeds) with mishri (rock sugar) after meals. It’s not a cure, but it helps with digestion and reduces cramps.

When You Need Medicine

  • If vomiting or diarrhea is non-stop, a doctor may prescribe antibiotics or antispasmodics.

  • IV fluids might be needed in cases of extreme dehydration.

  • Avoid popping antibiotics on your own—they don’t work on viruses, and can actually worsen things if misused.

Try not to eat spicy, oily, or dairy-heavy meals while you're recovering. Stick to simple, bland foods and hydrate constantly. Coconut water, lemon water with salt and sugar, or even plain water with a pinch of salt can go a long way.

Prevention Tips: How to Avoid Food Poisoning in India

It’s not always avoidable, but you can greatly reduce your risk with a few simple habits.

Food Safety at Home

  • Wash vegetables and fruits thoroughly, especially leafy greens.

  • Cook meats and eggs properly—don’t eat them half-done.

  • Keep raw and cooked food separate.

  • Refrigerate leftovers within 2 hours, not “next morning” style!

Smart Eating Outside

  • Choose vendors who cover their food and use clean water.

  • Say no to raw chutneys or salads outside, especially in summer or rainy season.

  • Always carry clean bottled water while travelling.
