Industrial production of insects for food and feed is associated with several challenges with regard to food and feed safety, including adjusting the current legislations to facilitate this new industry without risks to production animals and consumers. In 2019, the Danish Ministry of Food, Agriculture and Fisheries (MFVM) asked Aarhus University (AU), University of Copenhagen (KU), and the Technical University of Denmark (DTU) to frame the research needed to implement a sustainable industrial production of insects in Denmark. The current legislation prohibits feeding with several biomasses, which obviously would support a green transition in food and feed production Thus, it was pointed out that knowledge is needed on former foods and household waste, and on biomasses containing packaging material residuals. The intention is that the research based knowledge can support potential changes in EU regulations. The present report focuses on transfer of pesticide residues, perfluorakyl substances used on packaging material surfaces, and DNA from raw meat to larvae of the black soldier fly.
The topics of packaging materials and former food and household waste for insect production contain endless possibilities in setting up studies. The transition from the above mentioned overall aim to specific studies was a process involving key staff from the Danish Veterinary and Food Administration at MFVM, the authors of the current report representing the National Food Institute at DTU, and Department of Animal Science at AU. In collaboration it was specified which insect species and which feed components should be included in the studies to exemplify potential chemical and biological hazards. After aligning the expectation regarding the aim and objective of the studies, the university partners were responsible for choosing appropriate materials and methods to answer the objectives.
The present report presents the results of three sets of experiments performed to gain knowledge on the consequences for food/feed safety when growing black soldier fly larvae (BSFL) on feed spiked with chemical residues from packaging material, in this case perflourinated compounds. The larvae were housed at AU where the experiments were performed, and samples were shipped to DTU where chemical analyses were performed. Further, a literature study was performed to collect the available studies of potential risk parameters associated with insects as waste-to-feed converters, when produced for food or feed purposes.
