The LOD and LOQ were 0.5 lg kg1 and 1.5 lg kg1 for all analytes
(Table 3). The LOQ achieved allows for the identification and
quantification of target analytes below the maximum residue limits
(MRLs) established by the EU. The minimum required performance
limit (MRPL) for nitrofurans in poultry muscle and
shrimps is set at 1.0 lg kg1 by Commission Decision (EC)
2003/181/EC amending Commission Regulation (EC) 2002/657/EC.
