Abstract: Black Soldier Fly larvae (BSFL), Hermetia Illucens, are increasingly used as a new feed source in the EU. BSFL was proven to be able to convert and then recycle biowaste into high-quality nutrients for the feed industry. However, biowaste usually contains a lot of chemical hazards. Although BSFL are fed with these biowaste, the fate of the contaminants remains largely unknown, despite being a threat for both the insect industry and the higher trophic levels. The aim of this study was to profile BSFL in pesticides, mycotoxins, dioxins, furans, PCBs and PFAs and to link it with the levels of contamination of these chemical hazards in the substrates on which they had been reared. Larvae were reared on six different substrates; four authorized in the EU including carrots, apricots, salad and wheat bran and two currently unauthorized including school canteen and supermarket wastes. Rearing substrates and larvae 14 days old were analysed by two accredited labs (COFRAC): Inovalys (Angers, France) and Laberca (Nantes, France). Eighteen mycotoxins including aflatoxins, trichothecenes, fumonisins, ochratoxin, zearalenone and ergot alkaloid were searched. More than 500 pesticides, 18 PCBs dioxinlike and non-dioxin like, 7 dioxins (PCDD), 10 furans (PCDF) and 25 PFAS were also screened. The presence and concentrations of these chemical hazards in both rearing substrate and larvae will be discussed.
