What foods have antimicrobial agents in them? can you tell me what foods contain antimicrobial agents?

Organic foods: Many commercially raised foods are sprayed with several chemicals, pesticides, fungicides and others e.g. Apples may have six or seven or more sprays of different agents, so that any one agent is below government safety limits. Rarely are studies of the effect of multiple chemicals and pesticides on the people in general. Best way to try to protect yourself is by using organic foods.

Trace amounts: Many foods contain traces of antibiotic. Antibiotics are produced naturally by bacteria and fungi in soil, can be present on vegetables and fruit. Food animals (cattle, pigs, chickens, etc) often receive antibiotics and traces may be present in meat. There's too little in food to prevent or treat any infection, but sometimes enough to make your own natural bacteria resistant to common antibiotics.
