Are ionophores the same as antibiotics?
Yes. The United States Department of Agriculture Food Safety and Inspection Service (USDA-FSIS) classifies ionophores as antibiotics, due to how they work. However, the ionophores we use in raising our chickens ARE NOT in the same class of antibiotics used in humans. So, they do not apply to the discussion about antibiotic resistance in humans. In other words, they are “chicken” antibiotics, for lack of a better way of putting it.
