checking. In theory a check could be carried out to ensure the
quality of the product and these checks provide an indirect check
on the efficiency of cleaning. Thus, in practice, the checking of
effectiveness of cleaning depends upon the quality assurance for
the product, bearing in mind that a deterioration in quality is often
due to failure in cleaning.
2.5 It is recommended that samples should be accompanied by a
report which identifies the place, date and time of sampling including
any batch details and the name and designation of the sampling
personnel. When appropriate, the report should also include any
relevant conditions or circumstances (for example the ante-mortem
condition of the birds, post mortem findings, processing changes
which may arise from power failures, breakdown etc.).
3.0 INSPECTION AND SAMPLING PROCEDURES
3.1 Visual Inspection
3.1.1 An immediate and important impression of the cleanliness
of a production line in a poultry processing plant can be
obtained by visual inspection of the accessible parts
of a plant. These include all open containers, contact
surfaces, processing equipment and conveyor belts.
3.1.2 Visual inspection may be carried out using an ordinary
flashlight or by UV-light. Among many other confirmatory
tests the following may be applied to the surface under
examination.
a) No sign of fluorescence shall be detectable when the
surface is carefully inspected with long wave-length
(340 to 380mm) ultraviolet light.
b) A sterile spatula may be used to scrape a surface
carefully to demonstrate the presence of a film or
residues on improper cleaned equipment.
c) A piece of clean disposal muslin or tissue paper wiped
over metal surfaces of processing equipment will be
soiled if the surface is improperly cleaned.
