A highly practical two-tier approach involving a screening and a confirmatory method was set up to efficiently test histamine in fish products in the frame of official controls. After their validation, the routine management of the two procedures was simplified as far as possible ensuring a strict quality data control and maximizing the cost-effectiveness.(More)
The purpose of this study is to evaluate the degree of PCBs contamination of wild brown trouts (Salmo trutta trutta L) caught in Marche Region rivers and to study the percentage contribution of the sum of the six indicators PCBs with respect to the sum of eighteen congeners in wild brown trouts. The determination of eighteen PCBs was made on the edible(More)
Using high-performance liquid chromatography with diode-array detection (HPLC-DAD) technique, a confirmatory method for the determination of trace levels of tetracyclines (oxytetracycline, tetracycline, chlortetracycline and doxycycline) and their 4-epimers (4-epioxytetracycline, 4-epitetracycline and 4-epichlortetracycline) in animal tissues (muscle) was(More)
As a rainbow trout producer, Italy is accounted as fifth in the world and second in continental Europe. In this study, the levels of the eighteen PCBs in feed and in trout, showed a statistical significant difference (p<0.01) throughout the years, with a declining trend from 2005 to 2010. This trend shows effectively that quality and safety of trout feeds(More)
The Commission Decision 2002/657/EC is a fundamental reference document for the UE laboratories involved in residue analysis although its implementation has caused some difficulties in the requirements interpretation. In this work a pragmatic validation approach of a quantitative confirmatory method for the detection of 17-alpha-(alpha-NT) and(More)
One-hundred and thirty-four samples of mussels (Mytilus galloprovincialis) collected along Central Adriatic Sea in 2013 were examined to determine the levels of fifteen congeners of polybrominated diphenyl ethers (PBDEs). The purified samples were analysed by gas-chromatography coupled to tandem mass spectrometry (GC-MS/MS) applying the isotopic dilution.(More)
A gas-chromatographic single-quadrupole analytical method for the analysis of the 16 priority European Union (EU) polycyclic aromatic hydrocarbons (PAHs) in food is presented. The method fulfils the request of Regulation EU 836/2011 for an analytical procedure to be used for official control of PAHs in food in EU member states. The sample preparation(More)
