[Suitability of sampling methods for environmental studies in meat rendering and processing plants with European Community licenses].
In EC-licensed meat rendering and processing plants microbiological test results obtained through contact slides and a highly precise swab method were compared. It was revealed that when using contact slides the absolute cfu can be determined only after prior verification with a reference method. The key provided by the manufacturer for data interpretation does not always match with results obtained by swab technique. Nevertheless, contact plates are suitable to determine the microbiological status. However, their technical deficiencies must be compensated. A simple swab method is well suited for use in meat rendering and processing plants. It is very economical due to low material costs and easy to apply by plant hygienists. The use of a seven step scale listing results up to 10(3) cfu/cm2 enables even non-experts to interpret their results reasonably.
