Biosensor-based immunochemical screening assays for the detection of sulfadiazine (SDZ) and sulfamethazine (SMT) in muscle extract from pigs were developed. Samples were extracted with aqueous buffer and then centrifuged. This simple and straightforward preparation allowed up to 40 samples to be processed and analysed in 1 d. The limits of detection for the assays were found to be 5.6 ng g(-1) for SDZ and 7.4 ng g(-1) for SMT. These figures were well below the European and US legal limits for sulfonamides (100 ng g(-1)). The precision (RSD) between runs was
