Supply of data requirement to assess the safety of currently non-permitted waste streams to be used for rearing insects for feed
The Food Standards Agency commissioned Fera Science Ltd to provide chemical and microbiological data from a model insect rearing system. Black soldier fly larvae were raised on one of four currently non-permitted rearing substrates. Samples of the different rearing substrates, subsequent larvae and frass were taken for analysis of potential chemical and microbiological contaminants. Samples obtained from a UK insect producer using currently permitted rearing substrates were also included as a control.
