“…Because they are rich in proteins and micronutrients, such as Ca, Mg, Zn, Fe, and Cu, grasshoppers represent a potential food source (Anand and others ). To date, only a very small number of studies have been conducted to evaluate the microbial population within grasshoppers that are intended for human consumption (Giaccone ; Ali and others ; Klunder and others ; Osimani and others ; Stoops and others , Garofalo and others ). Even less investigated is the occurrence of transferable resistance in grasshopper food products available on the European market (Milanović and others ).…”

“…The DNA from the bacterial strains used as positive and negative controls was extracted as described by Osimani and others (). The PowerFood Microbial DNA Isolation Kit (Mo Bio Laboratories, Carlsbad, Calif., U.S.A.) was used for direct microbial DNA extraction from grasshoppers (Garofalo and others ).…”

“…For example, Garofalo et al. () identified a low abundance of reads, taxonomically assigned to Clostridium spp., Staphylococcus spp., Listeria spp. and Bacillus spp., previously not detected by culturable methods.…”

“…The pulverized larvae also contained 7.2 log CFU/g enterobacteria, 3.6 log CFU/g endospores, and up to 5.3 log CFU/g yeast and fungi [43,45,46]. The log CFU/g values decreased to less than two when the larvae were not completely pulverized before measuring the microbial load [48], but this could reflect the trapping of microbes in the gut, which would prevent their cultivation, although they would still be found in the final product. Even so, the high microbial load in the mealworms did not include typical food-borne pathogens such as Salmonella spp.…”

“…These are Gram-positive rod-shaped bacteria with probiotic properties in humans, although some species are opportunistic pathogens [51,52]. Another study found that the three dominant bacterial phyla were Tenericutes (44.2%), Proteobacteria (39.22%) and Firmicutes (13.09%), and the genus Spiroplasma was the most abundant OTU (44.1%) [48]. A third study confirmed the dominance of Tenericutes (36.6%), Proteobacteria (34.1%), and Firmicutes (26.2%), and at the genus level also Spiroplasma (38.7%) [53].…”
