A bacteriological survey of Raw Chicken Meat at retail shops in Ebetsu City from 1987 to 1992

Abstract

bacteriological survey was performed with chicken meat from two retail shops, A and B, in Ebetsu city of Hokkaido during the period 1987 to 1992. The geometric means of standard plate counts (SPC) and coliform counts (CC) per gram samples from shop B were 7.1×10⁶and 5.0×10⁵ (N=61) in 1987, 2.0×10⁶and 5.2×10⁴ (N=10) in 1990, and 4.7×10³and 1.6×10² (N=90) in 1992, respectively. The results were nearly the same with shop A. The isolation rates of Salmomella from shop B samples were 34%(N=61) in 1987, 40%(N=20) from March to August in 1990, 27%(N=52) from October 1990 to July 1991 and 8%(N=90) in 1992.
