93,0 * Antimicrobial Resistance Monitoring Program in Food-Producing Animals in Japan Tetsuo ASAI* National Veterinary Assay Laboratory, Ministry of Agriculture, Forestry and Fisheries, + +/ + Tokura, Kokubunji, Tokyo +2/ 2/++, Japan Summary Antimicrobial agents are essential for human and animal health and welfare, but antimicrobial use can lead to antimicrobial resistance. The resistance arising from antimicrobial use in food-producing animals represents a potential hazard to human medicine through foodborne infection caused by resistant bacteria. In Japan, the Japanese Veterinary Antimicrobial Resistance Monitoring System (JVARM) was formed in +333 in response to international concern about the impact of antimicrobial resistance on public health. In the JVARM program, initial monitoring for antimicrobial-resistant bacteria was carried out in +333 and then the first and second stages of the JVARM program were completed in,***,**- and,**.,**1, respectively. Veterinary antimicrobial use is a selective force for appearance and prevalence of antimicrobial-resistant bacteria in food-producing animals. However, antimicrobial-resistant bacteria are found in the absence of antimicrobial selective pressure. We show here the relationship between antimicrobial usage and prevalence of resistant bacteria under the JVARM from +333 to,**1..1.
