A composition and a method of using the composition for removal and prevention of broad spectrum foodborne microbial contamination in meat products is described. The method uses quaternary ammonium compounds for inhibiting attachment of and removing a broad spectrum of foodborne microbial contamination from poultry and meat products. For example, removing Escherichia coli O157:H7 contamination from meat and poultry products. One of the treatment methods is spraying quaternary ammonium compounds on the poultry and meat products to prevent broad spectrum foodborne microbial contamination. The treatment methods can contact the meat products with the quaternary ammonium compounds for less than 10 minutes and still obtain significant reduction of viable foodborne microorganisms. New formulations of quaternary ammonium compounds combined with glycerin and/or ethyl alcohol provides a concentrated formulation for industrial use and a more viscous formulation for use in spraying methods.
