Summer brings with itself a host of diseases, from typhoid to conjunctivities. Food poisoning is one such disease. Have you ever wondered why cases of food poisoning witness a surge in the hotter months? This article will explain it for you.
To understand this better, we reached out to Dr Pooja Pillai, Consultant, Internal Medicine, Aster CMI Hospital, Bangalore.
Why is Food Poisoning More Common in Summer?
Dr Pillai confirms that food poisoning is more common in summer. Explaining this, she says, “This is because warm weather helps bacteria grow faster in food. Germs such as E coli multiply quickly when food is kept outside or not stored properly. High temperature and humidity also make food spoil faster, especially milk, meat, and cooked dishes.”
The expert adds, “In summer, people often eat outside food, street food, or food that is kept uncovered for long hours. Drinking contaminated water or juices with ice can also increase the risk. Poor hygiene such as not washing hands before eating also adds to the problem.”

Common Symptoms of Food Poisoning
According to the Mayo Clinic, here are some of the common symptoms of food poisoning:
