“…Other fly species, such as the BSF, have shown similar capabilities of reducing pathogenic bacteria from the rearing medium. By culturing BSF larvae in spiked manure, S. Enteritidis and E. coli were reduced in poultry, pig and cow manure (Erickson et al, 2004;Liu et al, 2008), and S. Typhimurium in human faeces (Lalander et al, 2013).…”

A major barrier for using animal waste as substrate for production of insects for feed or food is the concern for safety of the end products. In this study we investigated how rearing of fly larvae of Musca domestica in poultry manure influenced the counts of three pathogenic test strains (Escherichia coli, Salmonella Enteritidis and Campylobacter jejuni) and investigated whether these were transferred from manure to larvae, pupae or adults flies. We monitored quantitative microbiological changes over a study period of seven days. We showed that the decay in the numbers of E. coli, S. Enteritidis, and C. jejuni was faster in manure with rearing of fly larvae than in manure without larvae; an 8 log10 reduction of all three test bacteria was observed within four days in manure with larvae; compared to manure without larvae where a 1 to 2 log10 was observed. We found no sign of propagation of the pathogens in the larvae gut. All test strains were detectable in low numbers at day 4 in the larvae gut but only C. jejuni survived until day 7. In the pupae, only S. Enteritidis was detectable at day 3, and no test strains were found later than day 3. None of the test strain was isolated from adult flies. The total aerobic bacterial count remained at a high level throughout the study both in manure, in larvae and in pupae. In conclusion, our results showed that elimination of the pathogens from the manure was accelerated by larvae rearing, but were still detectable at low number in the larvae gut until end of the larvae stage. This study provides data for evaluation of feed safety of fly larvae reared on animal waste. Furthermore suggests a potential use for reduction of these pathogens in manure.

“…2). It utilizes this waste and can simultaneously kill pathogenic bacteria such as Escherichia coli or Salmonella enterica present in, for instance, chicken or cattle manure (Erickson et al 2004;Liu et al 2008). It has even been proposed as a sanitation method for getting rid of human feces (Lalander et al 2013;Banks et al 2014).…”

With a growing world population, increasingly demanding consumers, and a limited amount of agricultural land, there is an urgent need to find alternatives to conventional meat products. Livestock production is, moreover, a leading cause of anthropogenic-induced climate change. To mediate this, more sustainable diets are needed, with reduced meat consumption or the use of alternative protein sources. Insects are promoted as human food and animal feed worldwide. In tropical countries, edible insects are harvested from nature, but overexploitation, habitat changes, and environmental contamination threaten this food resource. Therefore, sustainable harvesting practices need to be developed and implemented. We provide examples of (1) aquatic insects whose populations are threatened by pollution, (2) caterpillar species in Africa that are disappearing due to overexploitation and habitat change, (3) edible insects species that are considered pests in agro-ecosystems, and (4) edible insect species that can be conserved and enhanced in forest management systems. Insect farming can be conducted either on small-scale farms or in large-scale industrialized rearing facilities. We review the environmental sustainability of insect farming compared to livestock production. The major environmental advantages of insect farming compared to livestock production are as follows: (1) less land and water is required; (2) greenhouse gas emissions are lower; (3) insects have high feed conversion efficiencies; (4) insects can transform low-value organic by-products into highquality food or feed; and (5) certain insect species can be used as animal feed or aqua feed. For instance, they can replace fish meal, which is becoming increasingly scarce and expensive.However, edible insect species intended for production should be screened for risks to humans, animals, plants, and biodiversity.

“…In several studies, black solider fly larvae waste treatment systems have been shown to remove bacteria in the Enterobacteriaceae family: the concentration of Salmonella spp. was reduced by 7 log 10 in 8 days in a small batchoperated fly larvae system treating fecal sludge (Lalander et al 2013); Erickson et al (2004) observed the reduction of Salmonella enterica Serovar Enteritidis and Escherichia coli O157:H7 in cattle manure, while Liu et al (2008) have reported on the reduction of E. coli in poultry manure. However, a l t h o u g h a h i g h r e d u c t i o n i n b a c t e r i a o f t h e Enterobacteriaceae family occur, reduction of other organisms has not been observed.…”

The recycling of organic waste worldwide is not effective, which leads to water pollution and loss of potential crop fertilizers. Available resources have to be used more efficiently as the world population increases. An innovative solution is to use insects for the management of organic waste. Here, we used black soldier fly to convert organic waste into animal feed protein, as fly larvae, and plant fertilizer, as compost residue. A continuous fly reactor was monitored for 9 weeks. We analyzed physicochemical and microbial parameters, and we evaluated the sanitary risk. Results show 55.1 % of material degradation and 11.8 % of biomass conversion based upon total solids. We observed higher levels of N and P in the treatment residue than in the inflow material. Results also show a lower concentration of Salmonella spp. and viruses. Compost treatment with black soldier fly is therefore an efficient system for nutrient recycling.
