Proficiency Test for Inhibitors

Specially when it comes to such a sensitive tobic as the presence of veterinary drug residues in milk and milk products it is essential for every laboratory to optimally secure its own analysis results. This is shown by the high number of participants in the inhibitor proficiency tests. The aim of this proficiency test is to confirm that your routine inhibotor test analysis detects antibiotica residues in milkes commonly used inhibitors as penicillin G, cloxacillin and ampicillin with routine inhibitor analysis with MRL Level (maximum residue according to Regulation (EU) No. 37/2010) be verified by the participating laboratory.

We carry out this Inhibitor Proficiency Test with lyophilized samples from UHT milk regularly in the second half of the year.

Parameters, sample material and sample analysis:

This proficiency test covers 4 parameters with up to 4 concentration levels for whey, pasteurized, partielly homogenized milk/cream and skimmed milk (all cow milk). Furthermore 3 parameters with 3 concentration levels are offered for UHT milk and 6 further parameters with 3 or 4 concentration levels are offered for raw goat milk or raw buffulo milk (see annual program). Participation in all parameters is not obligatory, you have the possibility to sign up only for the parameter you interested in. All methods will be considered, i.e. “reference” and “alternative” method. Each analysis has to be performed under repeatability conditions. Statistical calculation will be done by QuoData GmbH.

Total Microbiological Count Proficiency Test

(not accredited)

The aim of this proficiency test is to confirm that you have successfully determined the total bacterial count in the raw cow´s milk with your routine bacterial count test. The test set consists of 10 samples covering different ranges of the total bacterial count.
