Contaminants in aquaculture: Overview of analytical techniques for their determination

Abstract

Highlights-Determination of contaminants in aquaculture samples is crucial for controlling food safety hazards.-Contaminants can enter in aquaculture mainly in feed and transferred to organisms.-We discuss analytical techniques for aquaculture contaminants.-The main contaminants are polychlorinated biphenyls, organochlorinated pesticides, and antibiotics.

Comprehensive overview of feed‐to‐fillet transfer of new and traditional contaminants in Atlantic salmon and gilthead sea bream fed plant‐based diets

“…Thus, available online tools on food safety have been constructed and updated over the last years under National and EU research projects for searching and comparing the levels of contaminants in different seafood products, including fish (https://sjomatdata.nifes.no/#search/; http://www.nutrigroup-iats.org/arraina-biomarkers). In particular, AQUAMAX (2006–2010) and ARRAINA (2012–2016) EU projects have highly contributed on this, providing valuable samples but also adequate analytical methods and approaches to assess the presence of potential contaminant residues in the aquaculture food chain (Justino et al., ; Nácher‐Mestre, Ibáñez, Serrano, Pérez‐Sánchez, & Hernández, ; Nácher‐Mestre, Serrano, Hernández, Benedito‐Palos, & Pérez‐Sánchez, ; Nácher‐Mestre, Serrano, Benedito‐Palos, et al., ; Nácher‐Mestre, Serrano, Portolés, et al., ; Nácher‐Mestre, Serrano, Benedito‐Palos, et al., ; Nácher‐Mestre et al., , ; Portolés, Garlito, Nácher‐Mestre, Berntssen, & Pérez‐Sánchez, ; Portolés, Ibáñez, et al., ; Regueiro, Negreira, & Berntssen, ). Advanced analytical methodologies based on the use of both gas chromatography (GC) and liquid chromatography (LC) coupled with low‐ and high‐resolution mass spectrometry (MS and HRMS, respectively) make feasible to analyse large lists of organic compounds (Portolés, Ibáñez, et al., ; Regueiro et al., ).…”

“…Besides, these specific contaminants, other nontarget (non‐pre‐selected) unknown and/or nonexpected undesirables, can potentially contribute to food safety of farmed fish. This is an analytical challenge that requires, among others, the application of wide‐scope analytical methodologies able to detect and identify a large number of very different potential undesirables in the aquaculture food chain as reported elsewhere (Hernández et al., ; Justino et al., ; Nácher‐Mestre et al., , , ; Portolés, Ibáñez, et al., ; Regueiro et al., ).…”

Trends in aquaculture sciences: from now to use of nanotechnology for disease control

Response of antimicrobial nitrofurazone-degrading biocathode communities to different cathode potentials

“…Antimicrobial agents have led to serious pollution of various environmental settings globally, including surface water and groundwater, estuary sediment and soils, for excessively abused in humans, domestic animals, and aquaculture (Justino et al, 2016;Van Boeckel et al, 2015;Yun et al, 2017b;Zhang et al, 2015). Nitrofurazone (5-nitro-2-furaldehyde semicarbazone, NFZ) is a broad-spectrum antimicrobial agent that belongs to nitrofurans.…”
