How does ants infect foods?

Ants can contaminate food by foraging and leaving pheromone trails that attract other ants to the food source. They often walk over surfaces, picking up bacteria and pathogens from their environment, which can then be transferred to the food they touch. Additionally, some species may regurgitate or excrete substances onto the food, further introducing contaminants. This behavior can lead to spoilage and potential health risks for humans who consume the contaminated food.
