“…For example, BSFL protein meal digest significantly inhibited C . perfringens growth ( Dong et al, 2021a ), and digests of BSFL protein meal, chitin-rich BSFL protein meal, and mealworm larvae powder were tested against C . difficile and significantly reduced the damaging effect of toxin A on cell mucosal layers produced by C. difficile ( Dong et al, 2021b ).…”

Insect-derived ingredients, including whole larvae, protein-rich meal, and oil, have been extensively studied in recent years and shown to be a sustainable source of quality nutrition for virtually all animal species and life stages. In addition to the ability to use these ingredients as a source of essential nutrition, more recent research has demonstrated the potential for the immunomodulatory activity of various components of insect-derived ingredients. For all insects studied, antimicrobial peptides make up a critical part of the insects’ innate immune system and these peptides have antimicrobial efficacy when purified from hemolymph and tested in vitro. From black soldier fly larvae, in particular, lauric acid is a predominant fatty acid deposited into the insect, and lauric acid also has potential antimicrobial activity in vitro and in vivo. Finally, the chitin and chitosan components of the insect exoskeleton may modulate microbial activity in a variety of ways. In companion animals, poultry, and livestock species, insect-derived ingredients have shown the potential to reduce the impact of actual or simulated disease challenge on several parameters of animal health and well-being. This review describes the current state of knowledge of the immunomodulatory potential of insect-derived ingredients.

“…As with Gram-negative bacteria, studies have shown BSFL suppression of Gram-positive bacteria. Species such as Clostridium perfringens , Micrococcus luteus , and Bacillus subtilis , as well as those of the lactobacilli and group D streptococci, have been suppressed in vitro by larval extracts ( 12 , 26 , 28 ). Analysis of some larval extracts by Dong et al ( 28 ) found lauric acid and medium-chain fatty acid derivatives in high concentrations with antimicrobial effects against Gram-positive bacteria ( 28 ).…”

Suppression of Methicillin-Resistant Staphylococcus aureus and Reduction of Other Bacteria by Black Soldier Fly Larvae Reared on Potato Substrate

Larvae of black soldier flies, Hermetia illucens , may be used to provide an environmentally sustainable and economically viable method for biological conversion of animal and plant wastes into ingredients of animal feeds on an industrial scale. However, contamination of harvested larvae by pathogenic microorganisms inhabiting decaying substrates may be a serious problem for wide-scale adoption of this technology.

“…The same study found that fecal N digestibility values for insect as food were similar to those of conventional protein sources. In vitro essays showed that fractions containing black soldier fly larvae protein significantly inhibited the growth of Clostridium perfringens, which is for 28% of the cases responsible for diarrhea in dogs (Dong et al 2021). However, Bosch and Swanson (2021) caution that health-promoting effects of insect products need to be studied more as well as the long-term impact of insects as food on the nutritional status of dogs and cats.…”

An overview is given on recent developments in insects as food and food by reviewing the literature which has appeared during the last few years on edible insects. An outlook to the future is provided. About a decade ago, the attention shifted from harvesting insects in the tropics to farming insects all over the world for food and feed applications. Most production is targeted towards pet food, but it will turn to aquafeed in the next two decades. More than 80% of all publications dealing with edible insects appeared during the last five years. Crickets and mealworms are used for human food while the black soldier fly is the main species used as animal feed. The criteria to choose insect species are automation, cheap substrates, disease avoidance, and market potential. Genetics are increasingly explored to improve production. The environmental impact of producing insects compares well to other alternative proteins, in particular their capacity to degrade organic waste streams. Edible insects are not only a good source of nutrients but also seem to provide health benefits not only for humans and animals, but also for plants (left over substrate). The challenge of convincing Western consumers is reviewed and whether sustainability is an issue. Processing techniques are being developed. The sector of insects as food and feed is developing fast thanks to an increasingly conducive legislative framework. It will progress further, provided that the insect industry, academia, governmental organizations, and public society closely cooperate.
