Summary

ANALYSIS OF SAMPLES TAKEN ON DIFFERENT OCCASIONS SHOWED THAT CONTAMINATION WITH THOSE TYPES OF PSYCHROTROPHIC COLIFORM BACTERIA OCCURRED MAINLY DURING PROCESSING. ALTHOUGH NOT FOUND IN THE CROP, SMALL INTESTINE OR CAECA OF FRESHLY SLAUGHTERED OR HUNG, UNEVISCERATED BIRDS, PSYCHROTROPHIC COLIFORMS COMPRISED 15-51% OF THE ENTEROBACTERIACEAE ON CARCASSES FOLLOWING EVISCERATION, OCCURRING ON NECK SKIN AT UP TO 1 M/G. THE MAJORITY OF STRAINS TESTED GREW IN LABORATORY MEDIA BETWEEN 271 AND 310 K (-2 AND 37 DEG C), WHILST THE DOUBLING TIMES AT 274 K (1 DEG C) IN MINCED CHICKEN BREAST (PH: 5.8) AND LEG MUSCLE (PH: 6.4) VARIED ACCORDING TO BOTH MUSCLE TYPE AND GROWTH CONDITIONS. THE ODOURS WERE GENERALLY LESS OFFENSIVE THAN THOSE ATTRIBUTED TO THE USUAL AEROBIC SPOILAGE BACTERIA.
