The magnitude of the risk of microbiological hazards was
estimated using laboratory analysis. Samples of poultry
carcasses were randomly collected from abattoirs, live bird
markets and farms, and processed using 3M™ Petrifilm™ Plates
for E coli Type I, Coliforms and Aerobic Plate Count as indicators
of contamination to assess the compliance with GHP and GMP,
considered relevant pre-requisites for HACCP.
