“…This biogenic amine is directly influenced by the level of histidine, which must be in excess of normal microbial growth requirements (Eitenmiller & de Souza, 1984); in all cases (except horse sausage by 28 d), the level of histidine remained essentially constant, so it appears that the excess release of that amino acid was used up in full to synthesize histamine. Taylor, Lieber, and Leatherwood (1978) reported similar results for histamine levels in various dry sausages; in Turkish sausages, histamine concentrations were 6.72-362.22 mg/kg (Şenöz et al, 2000) or 0.85-378.29 mg/kg (Bozkurt & Erkmen, 2002), but values as low as 50 (Stratton, Hutkins, & Taylor, 1991) and 100 (Eerola, Xavier, Lilleberg, & Aalto, 1997), and as high as 768 (Rabie et al, 2010) and 1000 mg/kg (Erginkaya & Varlik, 1989) have also been reported. The aforementioned levels will likely pose a risk for public health in the case of turkey sausages: recall that allowable limits for histamine are 40-100 mg/kg, and levels above 100 mg/kg may already cause some degree of poisoning (Maijala, Eerola, Aho, & Hirn, 1993).…”
