MeRA Test

Detection of antibiotic and sulphamide residues in meat by Geobacillus stearothermophilus.


Antimicrobial substances are given to cattle for therapeutic treatment of infections and so they can be present in meat as residual drugs. The presence of residual antimicrobial drugs in meat is a potential hazard for the consumers since those substances interfere with the intestinal flora, can cause allergic reactions and can contribute to the spreading of resistant microorganisms.

The detection of inhibiting substances in meat is ruled in Europe by Regulation 37/2010 EC and following modifications.

MeRA (Meat Rapid Antibiotic) Test is a microbiological test, set for the detection of residual antibiotics and sulphamides in meat, that uses spores of Geobacillus stearothermophilus and a culture medium designed for that purpose.


The test detects residues of antibiotics and sulphamides through their inhibition action against the growth in vitro, at 64 ± 0,5 °C, of Geobacillus stearothermophilus. The inhibition of bacterial growth is made evident by the presence of a fermentable sugar and a pH indicator in the culture medium.  


Each package contains:

50 tubes containing liquid culture medium;

50discs containing spores of Geobacillus stearothermophilus;

1 Instruction sheet.


Observe colour of the liquid in the tubes that, if green/blu, indicates antibiotic/sulphamide residues in the examined meat in concentrations above the detection limits; otherwise, a yellow/orange colour indicates the absence of antibiotic/sulphamide residues in the examined meat or their presence in concentrations under the detection limits.
