One of the most common problems during this season is Why Food Poisoning Increases in Summer, food poisoning. Many families in cities like Varanasi notice more cases of vomiting, diarrhea, abdominal pain, and weakness as temperatures soar.

Key reasons include:

1. Improper Food Storage
Food left outside even for a short time can become contaminated.
2. Contaminated Water
Drinking unsafe water is a major cause of infection during summer.
3. Street Food Consumption
Open food exposed to dust, flies, and heat can easily carry bacteria.
4. Unwashed Fruits and Vegetables
Eating fruits without proper washing increases infection risk.
5. Cross-Contamination
Using the same utensils for raw and cooked food can spread bacteria.
