Fish & Seafood
Does your seafood still meet your standards of quality? Fish, crustaceans and molluscs are among the most frequently traded food products in the world. Production is gradually shifting from wild-caught fish to aquaculture, under pressure from overfishing and the growing demand. As certain seafood products grow scarcer, unauthorised substitution by less exclusive species may sometimes take place.
Quality is related in part to the origin of the seafood species. TLR can identify fraud by tracing the origins of the fish or shellfish. In these analyses, we use DNA sequencing or PCR techniques. Another parameter that indicates quality is the freshness of the seafood products, which can be measured using the total volatile base nitrogen (TVBN). Threshold levels have been set for this value in the European Union, as well as for histamine levels. Spoilage can cause histamine levels to rise, possibly leading to food poisoning. TVBN and histamine assessment are also within the scope of TLR’s services.
Obviously, we also offer microbiological analyses, for instance for yeasts, fungi, E. coli, Bacillus, norovirus and Vibrio Spp. Nutritional content is also important. TLR can use measuring equipment to precisely determine levels of protein, fat, carbohydrates, water and vitamins. In addition, TLR can check for (environmental) contaminants and residues like pesticides, polycyclic aromatic hydrocarbons (PAHs), dioxins, PCBs, heavy metals, residues of veterinary drugs, and radioactive contamination.
TLR is ISO 17025-accredited (L059), QS-certified and approved by the FOSFA, FEDIOL and GLOBAL GAP. In this way we help your organisation to comply with (international) guidelines, such as the VLOG certification.
