A residue is a trace (microg kg(-1), ng kg(-1)) of a substance, present in a matrix. Residue analysis is a relatively young discipline and a very broad area, including banned (A) substances as well as registered veterinary medicinal products (B substances). The objective of this manuscript is to review future trends in the analysis of residues of veterinary(More)
Aflatoxin M₁ contamination in dairy products is a risk when feedstuff contaminated with aflatoxin B₁ produced by moulds is consumed by milk-producing animals. Milk can be screened for aflatoxin M₁ at the European Union maximum limit of 50 ng l⁻¹ by a lateral flow test, the MRLAFMQ (Aflatoxin M1) Test. The method takes 15 min with no milk dilution or a(More)
The 2-min protocol (1 + 1) for the betaeta-s.t.a.r. (manufactured by Neogen Corporation, Lansing, MI, USA) was validated at the Technology and Food Science Unit of the Institute for Agricultural and Fisheries Research according to Commission Decision 2002/657/EC. The test was very selective for the group of beta-lactam compounds: the only interference found(More)
Regarding anti-infectious agents, no maximum residue limits are fixed for honey in the European legislation. Discussions are being conducted in order to set working limits at the European level; for example, for tetracyclines, 20 microg/kg was proposed. The Tetrasensor Honey test kit is a receptor-based assay using dipsticks for a rapid screening (30 min)(More)
The 2-min protocol (1þ 1) for the eta-s.t.a.r. (manufactured by Neogen Corporation, Lansing, MI, USA) was validated at the Technology and Food Science Unit of the Institute for Agricultural and Fisheries Research according to Commission Decision 2002/657/EC. The test was very selective for the group of -lactam compounds: the only interference found was by(More)
The biochemicals utilized in the Charm MRL beta-Lactam test (8 min test) were applied to faster flowing lateral components to create a new 3 min, one-step beta-lactam test called Charm MRL-3 (Charm Sciences Inc., Lawrence, MA). This new test was validated at T&V-ILVO according to Commission Decision 2002/657/EC. The following analytical parameters were(More)
The SNAP was modified to SNAP ST (Idexx Laboratories Inc., Westbrook, ME), a new 7-8 minute test which no longer requires the use of an incubator. This new test was validated at ILVO-T&V according to Commission Decision 2002/657/EC and the CRL Guidelines for the Validation of Screening Methods (Anon., 2010). The SNAP ST is very specific as an interference(More)
