Sm. Russell et al., THE EFFECT OF TEMPERATURE MISHANDLING AT VARIOUS TIMES DURING STORAGEON DETECTION OF TEMPERATURE ABUSE OF FRESH BROILER CHICKEN CARCASSES, Poultry science, 75(2), 1996, pp. 261-264
Experiments were conducted to determine the effect that temperature mi
shandling at various times during storage has on detection of temperat
ure abuse of fresh broiler chicken carcasses using populations of meso
philic and coliform bacteria as indicators of abuse. Forty-five broile
r carcasses were used in each of three independent trials. Five carcas
ses were analyzed at day of collection (Treatment 0 control). Five car
casses, on each day of the next 7 d (Treatments 1 to 7) were temperatu
re-abused for 12 h at 25 C, stored at 3 C until Day 9, and then sample
d. The five remaining carcasses were stored at 3 C and sampled on Day
9 (Treatment 8 control). Carcasses were sampled using a whole carcass
rinse procedure and assayed for aerobic plate counts (APC), total coli
form counts (TCC), impedance detection times (DT), and impedance colif
orm detection times (DTCM). Although significant differences were note
d using all four microbiological methods, temperature abuse at differe
nt times during storage had no consistent effect on populations of mes
ophilic or coliform bacteria; therefore, temperature abuse determinati
ons may be conducted without regard to the day on which the carcasses
were subjected to elevated temperatures.
