Experiments were conducted to determine whether lots of broiler chicken carcasses analyzed at Day 0 or subjected to various refrigeration or freezing temperatures could be microbiologically differentiated using impedance microbiological methods. Sixty ready-to-cook broiler chicken carcasses were collected from a processing facility and used in each of three replicate trials. For each trial, 10 carcasses each were: sampled immediately (Day 0 control), sampled after holding at 3 C for 13 d (Refrigerated control), sampled after holding at 0 C for 12 d and tempering at 3 C for 24 h (Refrigerated 0), sampled after holding at -3.9 C for 12 d and tempering at 3 C for 24 h (Frozen -3.9), sampled after holding at -7.8 C for 12 d and tempering at 3 C for 24 h (Frozen -7.8), and sampled after holding at -27.0 C for 12 d and tempering at 3 C for 24 h (Frozen -27). Carcasses were sampled using a whole carcass rinse procedure. Mesophilic impedance detection times (MDT) and coliform impedance detection times (CDT) at 42 C were conducted in duplicate on each carcass rinse. Lots of carcasses held at 0 C or below had significantly fewer mesophiles than those held at 3 C. The MDT would be suitable for distinguishing carcasses held at 0 C or below from those held at 3 C. Using CDT, lots of carcasses frozen at -7.8 or -27.0 C could be distinguished from lots analyzed at Day 0 or held at 0 or 3 C. Using CDT, lots of carcasses frozen at -3.9 could not be separated from those held at 3 C, but could be distinguished from those held at 0 C. Monitoring coliforms using impedance would be useful for identifying lots of carcasses subjected to temperatures of -7.8 C or below but would not be suitable for determining freezing temperature. |
