Abstract

食鳥と体の細菌検査に関して3つのサンプリング方法 (皮膚表面の拭き取り, 皮膚の採取, と体全体のリンス) を比較した. 成鶏と体20例の試験において, 皮膚採取法あるいはリンス法の生菌数は拭き取り法より有意に高かった. カンピロバクターはリンス検体で8例, 皮膚検体で4例, 拭き取り検体で1例検出された. この結果からリンス法は他の方法よりも優れていると思われた. 加えてブロイラー処理場で中抜き工程と水切り工程間のと体の細菌汚染を調査した. 指標菌数, カンピロバクターおよびサルモネラの陽性率は, 水切り後と体において著しく減少した. しかし45例のと体からカンピロバクターが6.7%, サルモネラが56%分離された.

Three sampling methods (skin-surface swabbing, excised-skin sampling, and whole-carcass rinsing) were compared for bacteria recovery from poultry carcasses. In an experiment with 20 layer carcasses, total viable counts obtained by skin sampling were significantly higher than those obtained by swabbing. <I>Campylobacter</I> was detected on 8 rinsed and 4 excised samples and on 1 swabbed sample. These results suggest that the whole-carcass rinse method is superior to the other methods. In addition, bacterial contamination of carcasses was analyzed between the evisceration stage and rinse-method drip at a broiler-processing plant. Indicator organisms and positive reaction for <I>Campylobacter</I> and <I>Salmonella</I> were significantly lower after rinsing. Nonetheless, <I>Campylobacter</I> was isolated from 6.7% and <I>Salmonella</I> from 56% of 45 cases
