The management of Chinese food safety is not optimistic right now. The mainly cause of this problem is the degree of food information in low procurement, production, circulation, and other aspects. Whether the government supervision departments or social forces are difficult to comprehensively collect and master the information related to food security. It can not form a timely and effective regulation. In the contrast, information technology is applied to the important link of the food safety management in the United States, the European Union and other developed countries or regions.

The physical characteristics of bacteriophages establish them as viable candidates for downstream development of pathogen detection assays and biocontrol measures. To utilize phages for such purposes, a detailed knowledge of their host interaction mechanisms is a prerequisite. There is currently a wealth of knowledge available concerning Gram-negative phage-host interaction, but little by comparison for Gram-positive phages and Listeria phages in particular. In this research, the lytic spectrum of two recently isolated Listeria monocytogenes phages (vB_LmoS_188 and vB_LmoS_293) was determined, and the genomic basis for their observed serotype 4b/4e host-specificity was investigated using comparative genomics.
