Comparison of Two Control Methods of Decontamination in a Poultry Slaughterhouse

A study concerning the technical validity of two control methods of cleaning and decontamination in Batna’s poultry slaughterhouse has been realized to verify their reliability. The first method is based on the counting of total germ colonies (cfu) thanks to petri dish (Rodac PCA®) used on different surfaces of the slaughterhouse sectors (quay of reception, slaughtering room, evisceration room, meats …) after decontamination. The second method (Kit PRO 3S®) permits to put in evidence the presence of dirty on a visibly clean surface; it is based on the detection of proteins (µg/test) on the different surfaces inside the slaughterhouse (soil, wall, scale, chain, blood tray, drier, carpet…). The results of this experiment showed that there is a positive correlation between the two methods.
