Annex Reference points for action (RPA)
United Kingdom
| Due to the natural occurrence of SEM in crayfish at levels above the RPA, only levels of AOZ, AMOZ, AHD and DNSH above the RPA are a clear indication of the illegal use of nitrofurans and their metabolites. The RPA of 0,5 µg/kg for SEM in crayfish shall only be applied, when the illegal use of nitrofurazone on crayfish has been established. | ||
| Substance | RPA(µg/kg) | Other provisions |
|---|---|---|
| Chloramphenicol | 0,15 | |
| Malachite green | 0,5 | 0,5 µg/kg for the sum of malachite green and leucomalachite green |
| Nitrofurans and their metabolites | 0,5f1 | 0,5 µg/kg for each of the metabolites of furazolidone (AOZ or 3-amino-2-oxazolidinone), furaltadone (AMOZ or 3-amino-5-methylmorpholino-2-oxazolidinone), nitrofurantoin (AHD or 1-aminohydantoin), nitrofurazone (SEM or semicarbazide) and nifursol (DNSH or 3,5-dinitrosalicylic acid hydrazide) |
