Code of Veterinary Practice For Poultry Processing Plant
3.2.3.2 The sampling methods used could be:
a) Suction of a known volume of air through a suitable
filter, buffer solution or nutrient broth.
b) Exposure of air plates for a certain period of time.
The objective of both methods is to determine the number of organisms
in the filter, buffer solution or nutrient broth or on the plates. The sampling
time for all methods of collection is usually standardized at 15, 30 and
60 minutes, the duration being determined by experience or estimation.
Samples may be taken monthly to detect specific micro-organisms unless
more frequent sampling is necessitated by emergency conditions or
suspected contamination.
3.2.4 Water and aqueous solutions other than those
added to the product.
3.2.4.1 Sampling of water and aqueous solutions should be
carried out while the material is in motion and care shall be
exercised to ensure that the samples are representative
of the homogeneous mixture.
3.2.4.2 All cleaning solutions should be tested before use in
order either to confirm that the concentration is correct
to calculate any adjustments needed to obtain this
concentration.
Routine monitoring of the amount of detergent which is necessary for
cleaning will indicate any abnormal demand which could be the result of
heavy deposits on the plant surfaces.
3.2.5 Products
3.2.5.1 One method of assessing the hygienic state of a poultry
processing plant is to check the bacteriological condition
of the product.
3.2.5.2 Bacterial Count on Surface of Raw Poultry Parts.
a) Obtain tare weight of sterile plastic sampling bag
(about 0.05mm thickness).
