THE CASE FOR IONOPHORES
Unlike other classes of antibiotics, ionophores are not considered important to human health by top public health and regulatory agencies.
Earlier this year, when McDonald’s USA announced it would require chicken suppliers to phase out antibiotics, the fast-food giant made one notable exception. It gave a pass to a class of antibiotics called ionophores - medications like monensin, salinomycin, lasalocid, to name a few. In this in-depth report, Poultry Health Today looks at the science behind ionophores, how they’re different from other antimicrobials and why it should matter to poultry marketers.
