How can you tell someone put something in your food that will make you sick?

If you suspect someone has tampered with your food, look for unusual tastes, smells, or textures that are not characteristic of the dish. Additionally, if you experience sudden nausea, vomiting, or other symptoms shortly after eating, it may indicate contamination. Trust your instincts; if you feel something is off, it's best to avoid consuming the food and seek medical advice if needed.
