Abstract

Disclosed are antimicrobial compositions for treating poultry, meat, and other surfaces to substantially eliminate bacteria and microorganism harmful to humans. The compositions include a combination of an aliphatic heteroaryl salt, trichloromelamine, and at least two ammonium salts comprising an aliphatic benzylalkyl ammonium salt, dialiphatic dialkyl ammonium salt, or a tetraalkyl ammonium salt.
