The demand for digestate biofertilizer is dependent on compliance with quality standards (Alburquerque et al., 2012). Though the use of digestate biofertilizer to increase agricultural food production, and soil improvement has been established, its safety as determined by the amount of pathogens contained is still of public health concern to end users (Alfa et al., 2014). Reports on the fertilizer and sanitary quality of digestate from anaerobic digestion are scanty in scientific literature, despite the large vol- ume of literature on biogas yield from various substrates. However, the fertilizer potential of digestate from farm and agro-industrial residues was investigated by Alburquerque et al. (2012). Johansen et al. (2013) have also reported that digestate biofertilizer increases soil microbial community. Alfa et al. (2014) have assessed the biofertilizer quality of digestate from the digestion of cow dung and chicken droppings. The properties of guinea pig manure digestate were reported by Garfi et al. (2011
