Abstract: A system and method for reducing or preventing bacterial contamination in food includes application of a bacteriophage treatment to any type of food product at any stage of processing the food product. The bacteriophage treatment may also be applied to non-food surfaces and water systems, which may be susceptible to bacterial contamination and subsequent spread of bacteria. The bacteriophage treatment comprises at least one bacteriophage in a concentration sufficient to reduce or prevent bacterial contamination from pathogenic bacteria and/or spoilage bacteria. In some embodiments, the bacteriophage is able to reduce or eliminate bacteria introduced to a food product after the bacteriophage treatment was applied to the food product. In some embodiments, the bacteriophage treatment includes a buffering agent to maintain the bacteriophage at a pH level that sustains the bacteriophage. In some embodiments, the bacteriophage treatment includes a surfactant and/or a thickener to aid in applying the bacteriophage. Additional adjuvants and enhancers may be used in some embodiments to stabilize the bacteriophage or enhance its performance as an antibacterial agent.

Abstract: Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C2-C4 peroxycarboxylic acid and a C8-C12 peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C2-C4 peroxycarboxylic acids and one or more C8-C12 peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

Abstract translation: 用于减少或防止食品中细菌污染的系统和方法包括在加工食品的任何阶段对任何类型的食品进行噬菌体处理。 噬菌体处理也可以应用于非食品表面和水系统，其可能易受细菌污染和随后的细菌扩散。 噬菌体处理包括至少一种浓度足以减少或防止病原菌和/或腐败细菌的细菌污染的噬菌体。 在一些实施方案中，噬菌体在将噬菌体处理应用于食品后能够减少或消除引入食品的细菌。 在一些实施方案中，噬菌体处理包括将噬菌体保持在维持噬菌体的pH水平的缓冲剂。 在一些实施方案中，噬菌体处理包括表面活性剂和/或增稠剂以有助于施用噬菌体。 在一些实施方案中可以使用另外的佐剂和增强剂以稳定噬菌体或增强其作为抗菌剂的性能。
