This disclosure provides generally for antimicrobial compositions and methods for reducing or preventing microorganism growth, viability, or survival, which are useful for treating poultry, meat, seafood, vegetables, legumes, fruit, crops, and other products for human or animal consumption. For example, the compositions can include GRAS (Generally Recognized As Safe) antimicrobial components such as ε-poly-L-lysine in combination with at least one quaternary ammonium salt, including an aliphatic heteroaryl ammonium salt such as cetylpyridinium chloride. 1. An antimicrobial composition comprising:a) ε-poly-L-lysine; andb) at least one quaternary ammonium compound.2. An antimicrobial composition according to claim 1 , wherein the ε-poly-L-lysine contains from about 20 to about 40 L-lysine residues.3. An antimicrobial composition according to claim 1 , wherein each of the at least one quaternary ammonium compound is selected independently from an aliphatic heteroaryl salt claim 1 , an aliphatic benzyl dialkyl ammonium salt claim 1 , a dialiphatic dialkyl ammonium salt claim 1 , and a tetraalkyl ammonium salt.4. An antimicrobial composition according to claim 1 , wherein each of the at least one quaternary ammonium compound is selected independently from an aliphatic heteroaryl salt and an aliphatic benzyl dialkyl ammonium salt.5. An antimicrobial composition according to claim 3 , wherein the aliphatic heteroaryl salt is selected from cetylpyridinium chloride claim 3 , cetylpyridinium bromide claim 3 , and a combination thereof.6. An antimicrobial composition according to claim 3 , wherein the aliphatic benzyl dialkyl ammonium salt is selected from alkyl dimethyl benzyl ammonium halide claim 3 , alkyl diethyl benzyl ammonium halide claim 3 , alkyl methylethyl benzyl ammonium halide claim 3 , and a combination thereof.7. An antimicrobial composition according to claim 3 , wherein the dialiphatic dialkyl ammonium salt is selected from didodecyl dimethyl ammonium halide ...
