POULTRY, MEAT, FISH AND EGG SCAN
Antibiotics are used in animal husbandry for the treatment and prevention of diseases. To avoid
undesired residues of these substances in edible tissues, maximum residue limits (MRL’s) have been
established in the EU. Products produced in the EU have to fulfill these residue requirements. Self-
monitoring by the meat-industry, farmers and retailers is an important tool to ensure the consumer
safety with regard to antibiotic residues.
For this purpose RIKILT developed the SCAN tests (SCAN = SCreening ANtibiotics). The SCAN tests
are novel microbiological screening methods for the detection of antibiotic residues in fresh meat
(poultry, pig and bovine), fish and eggs. The tests are ideal for use 'on site'. The tests are:
 fast and reliable; reliable result are obtained in less than 12 hours (overnight incubation)  able to classify the antibiotic residue: The tests enable class identification (e.g. tetracyclines,  suited for on-site application: easy handling; only an incubator and a pipette is needed to conduct the test, no apparatus is needed to interpret the results  positive control samples are included; positive control samples guarantee the performance of the tests; comparison with the positive control samples gives a first insight in the level of contamination (= semi-quantitative test) Figure 1: an example of the POULTRY SCAN test The SCAN test allows farmers, slaughterhouses, processors and retailers to cost-effectively screen on the presence of residues of antibiotics in poultry, meat, fish and eggs. The SCAN tests are extremely sensitive, and are detecting a large variety of antibiotic residues in these products. The detection limits are at or below the maximum residue levels set by the European Union.

For information please e-mail The SCAN tests are based on the direct application of meat fluid (meat, poultry or fish drip) or homogenized egg onto a microbiological plate system. The system comprises a separate test plate for each class of antibiotic (tetracyclines, quinolones, sulphonamides, macrolides/ß-lactams). The detection of ß-lactams and macrolides is combined in one test. Meat fluid can be obtained in several ways:  freezing and defrosting  gentle heating (60°C) The meat juice (or homogenized egg) is pipetted into holes in the test plate. Each test plate contains 9 holes, allowing the simultaneous analysis of 8 samples and 1 positive control sample. After the holes are filled, a drop of a specific reagent is added to each hole and the test plates are incubated overnight at 30°C. The presence of antibiotic-residues is shown by the formation of zones of inhibition around the holes. (see Figure 1). The test plate showing the largest inhibition zone reveals the class identity of the antibiotic present. Confirmation by instrumental analytical methods (LC-MS) is necessary to verify whether EU MRLs are exceeded. The positive control sample should give a zone of inhibition. If this is not the case, the analysis is not valid and has to be repeated. Absence of inhibition zones indicates the absence of residues of veterinary drugs exceeding the Figure1: A sample without inhibition zone (negative) and a legal limits in meat or eggs (see appendix). The POULTRY and MEAT SCAN tests are validated according to EU guideline 2002/657/EC. The
detection capacities (95% limits of detection) of the methods are given in the Appendix.
History and current use
The Poultry SCAN test is developed and validated in 2002/2003 and commercially available since
2004. Currently the test is recommended by the Dutch Poultry processing industry for their self-
control program on antibiotic residues. In the 2005 approximately 25.000 chicken breasts were
screened with the POULTRY SCAN test for tetracyclines or quinolones.
Since the introduction of the Poultry SCAN test in 2002, new tests have been developed,
respectively Meat SCAN (2003), Fish SCAN (2004) and Egg Scan (2005). The production of these
tests for the Dutch market is growing.

Die schwangerschaft

Die Geburten meiner zwei Töchter – einmal ohne und einmal mit Traude. Kein Vergleich! BEL und Sophie Licht! Die Schwangerschaften Ich habe zwei gesunde Kinder (Sophie-Therese 2003, Amelie-Louise 2006) zur Welt gebracht und dennoch lässt sich dieses Kapitel ganz kurz halten: ich bin/war sehr gerne schwanger! Ich konnte es jedes Mal unheimlich genießen schwanger zu sein.
