Did anyone experience severe food poisoning on the south coast.

Always stick to eating hot, freshly cooked food like kottu or hoppers that are prepared on a scorching grill right in front of you. The high heat kills almost all bacteria, making it incredibly safe.

Totally avoid eating pre cut fruit sold by street vendors that has been sitting out in the sun. The fruit itself is fine, but it is frequently washed with tap water or sliced with unhygienic knives.
