“…Data on the bioaccumulation factor of heavy metals in different life stages of BSF suggest that metals like copper, iron, mercury, magnesium, selenium, zinc, and molybdenum are accumulated in the biomass. For the first time, the concentrations of chosen non-essential elements Ba, Bi, Ga, which undergo bioaccumulation, and elements Al, Si, which do not undergo bioaccumulation in BSF was reported [152]. According to Bosch et al [153] BSFL and TM exhibit high aflatoxin B 1 tolerance and does not accumulate in BSFL biomass.…”

Each year, the food supply chain produces more than 1.3 billion tons of food and agricultural waste, which poses serious environmental problems. The loss of the massive quantity of secondary and primary metabolites retrievable from this resource is a significant concern. What if there is a global solution that caters to the numerous problems arising due to the humongous volume of waste biomass generated in every part of the world? Insects, the tiny creatures that thrive in decaying organic matter, which can concentrate the nutrients present in dilute quantities in a variety of by-products, are an economically viable option. The bioconversion and nutritional upcycling of waste biomass with insects yield high-value products such as protein, lipids, chitin and frass. Insect-derived proteins can replace conventional protein sources in feed formulations. Notably, the ability of the black soldier fly (BSF) or Hermetia illucens to grow on diverse substrates such as agri-food industry side streams and other organic waste proves advantageous. However, the data on industrial-scale extraction, fractionation techniques and biorefinery schemes for screening the nutritional potential of BSF are scarce. This review attempts to break down every facet of insect processing and analyze the processing methods of BSF, and the functional properties of nutrients obtained thereof.

“…The easiest initial approach to mitigate this concern would be to utilize BSFL reared on a clean "waste," in controlled farming environments to reduce the potential associated risks such as heavy metal uptake and potential pathogenic microorganisms (Rumpold & Schlüter, 2013;Wang & Shelomi, 2017). Although BSFL have primarily been farmed for animal feed purposes, resulting in little knowledge regarding the food safety risks of consuming BSFL, there is a large body of information regarding the safety of using BSFL for animal consumption when reared on a wide range of waste substrates, most of which could also be relevant to using BSFL grown on waste for uses in human food (Gold et al, 2018;Lalander et al, 2014;Liu et al, 2008;Proc, Bulak, Wiącek, & Bieganowski, 2020;Wang & Shelomi, 2017;Wanjiku, 2018;Wynants et al, 2019), with postharvesting processes such as blanching as an effective safety tool/hurdle (Klunder, Wolkers-Rooijackers, Korpela, & Nout, 2012; Larouche et al, 2019).…”

“…A potential concern with using BSFL grown on "waste" streams is the accumulation of heavy metals in their biomass. BSFL have shown to accumulate heavy metals such as cadmium, mercury, copper, and lead, which are known to have adverse effects on human health when consumed in excess (Jaishankar, Tseten, Anbalagan, Mathew, & Beeregowda, 2014;Proc et al, 2020;Schrögel & Wätjen, 2019). Heavy metals such as copper and cadmium are found to have a negative impact on the gut microbiome of BSFL, which in turn could severely affect their ability to effectively reduce microorganisms in the feed.…”

“…In fact, accumulation of copper and cadmium did enrich the growth of potentially pathogenic bacteria, which may find its way into the food if not effectively managed (Wu et al, 2020). The heavy metal content of the feed directly impacts the heavy metal content in the larvae (Diener et al, 2015;Proc et al, 2020) and therefore it is important to monitor the heavy metal content in the feed to mitigate the toxic risks to humans. To date, studies have indicated that BSFL do not accumulate mycotoxins, pharmaceuticals, or pesticides found in substrate due to their innate detoxification processes (Gold et al, 2018;Lalander et al, 2014;Purschke, Scheibelberger, Axmann, Adler, & Jäger, 2017).…”

With the surge in consumption of insects, the search continues to find ways to increase the popularity of insect‐based products in the Western world. The black soldier fly larvae (BSFL), which is mainly utilized for animal feed, has great potential to provide a sustainable source of nutrients for human food. This review aims to discuss some of the key benefits and challenges of BSFL and their potential role as a food ingredient and/or product for human consumption. Few articles specifically discuss BSFL as a food source, therefore a comprehensive literature search strategy consisted of collecting and evaluating published data about BSFL as animal feed that could be relevant to its use in food. The hurdles that need to be overcome in order to introduce BSFL as a viable food option include safety concerns, technofunctional properties, nutritional aspects, consumer attitudes, and product applications for BSFL.

Until now, the term entomotoxicology has only been used in medico-legal sciences. However, entomotoxicology as a whole has a much wider scope and forensic entomotoxicology is just one of its branches. Based on the literature a wider definition of the term is presented. Today, we can distinguish two major branches of entomotoxicology : 1) Forensic entomotoxicology , which uses the insects as evidence of the presence of xenobiotics in decomposing tissue during an investigation and 2) Environmental entomotoxicology , which uses the insects as bioindicators of environmental pollution in non-criminal circumstances. While forensic entomotoxicology is a relatively new discipline, research in environmental entomotoxicology began as far back as the 1920s. A review of the work in entomotoxicology from the last 6 years is presented, covering several interesting new trends. This article aims to redefine entomotoxicology, which should increase awareness to bring more collaborations and multidisciplinary between related scientific fields.
