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. Fig 1 Shows the poultry value chain as a flow diagram, for each type of processor in MaputoThe contamination rate with E. coli Type I was significantly The magnitude of the risk for a single consumer can behigher in live bird markets (63%) than formal abattoir (39%) estimated from market segmentation, based on the estimatedand farms (40%). The Coliforms was significantly higher in number of fowls slaughtered per week per outlet type.abattoir (41%,) than farms (21%) and live bird market (6%). The Although the highest proportion of contaminated carcasses isAPC was significantly higher in live bird markets (87%) than from the live birds markets, the largest number of contaminatedformal abattoir (64%) and farms (44%). poultry carcasses comes from the high throughput abattoirs.
