Mitt arbeidsfelt er uønskede stoffer i oppdrettsfisk, jeg jobber både med legemidler og miljøgifter. Jeg er også involvert i metodeutvikling på rester av legemidler ved bruk av væske kromatografi-massespektroskopi (LC-MS/MS).



Arbeidsområde

Vitenskaplige publikasjoner


Jeg er prosjektleder for et overvåkningsprogram for uønskete stoffer i oppdrettsfisk. Dette prosjektet blir gjort i henhold til EU directive 96/23  "on measures to monitor certain substances and residues thereof in live animals and animal Products ". Dette direktivet sier at man skal undersøke en oppdrettsfisk per 100 tonn produsert, for uønskete stoffer, i 2013 ble ca 12500 fisk analysert. Fisken kan bli analysert for ulovlige stoffer som stibener og steroider eller ulovlige legemidler som f.eks. nitrofuraner og kloramfenikol. Prøver blir også sjekket for rester av legemidler, samt organiske miljøgifter og tungmetaller. Hvert åt blir det publisert en rapport med resultatene fra dette overvåkningsprosjektet.


Jeg jobber mye relatert til metodeutvikling for bestemmelse av legemiddel rester i oppdrettsfisk. Når det blir brukt legemidler på oppdrettsanlegg så skal det være en tilbakeholds periode før fisken blir slaktet slik at eventuelle rester av legemidler skal være under grenseverdien til det aktuelle legemiddelet. Vi analyserer fisk for å sjekke at eventuelle medisinrester er under grenseverdiene. Vi analyserer for både lusemidler, antibiotika og legemidler brukt mot innvollsparasitter. I tillegg til å analysere for rester av veterinære legemidler så analyserer vi også for ulovlige legemidler, vi har metoder for flere antibiotika og fargestoff som er forbudt å bruke til oppdrettsfisk. Prøvene blir analysert ved bruk av væske kromatografi-massespektroskopi (LC-MS/MS).
