ORIGINAL_ARTICLE Tuna is a food widely consumed fresh and canned as well. After catching and filleting, a pre-cooking step is normally followed by freezing and shipping to canning industry as loins. The aim of this paper was to assess the microbiological quality and safety of tuna loins (50 samples) imported by an Italian canned tuna producer from two different FAO fishing areas. Total bacterial count (TBC), Coliforms, Enterobacteriaceae, Escherichia coli, Listeria monocytogenes, Salmonella, Staphylococcus aureus, Vibrio parahaemolyticus, Vibrio cholera, pH measurement, S. aureus enterotoxin and histamine levels were evaluated. Significant differences were evidenced for TBC, Enterobacteriaceae, E. coli, Coliforms and pH between fishing areas. Staphylococcus aureus was detected in all the samples tested at 1 to 3 Log cfu/g; Staphylococcus warneri, S. saprophyticus, S. epidermidis, S. hominis, S. intermedius, S. vitulinus and S. sciuri were also identified. Listeria monocytogenes, Salmonella, Vibrio parahaemolyticus, Vibrio cholera and Staphylococcus aureus enterotoxin were not detected. Histamine ranged between 0 to 5 mg/kg. The tuna loins analysed in this paper have to be considered safe; staphylococci presence represents a possible concern and has to been taken in account when risk analysis is carried out. https://macvetrev.mk/Files/Article/2020/10.1515/macvetrev-2017-0028/macvetrev-2017-0028.pdf 2018-03-15T09:00:00 33 37 10.2478/macvetrev-2017-0028 tuna loins Katsuwonus pelamis canned tuna Staphylococcus aureus histamine Francesco Casalinuovo false 1 Institute for Experimental Veterinary Medicine of Southern Italy, Viale Crotone 88100 Catanzaro, Italy AUTHOR Donatella Brindisi false 2 Quality Manager Intertonno Srl, Zona Industriale Lotti 20/21 89843 Maierato (VV), Italy AUTHOR Paola Rippa false 3 Institute for Experimental Veterinary Medicine of Southern Italy, Viale Crotone 88100 Catanzaro, Italy AUTHOR Carlotta Ceniti false 4 Department of Health Sciences, Magna Graecia University, Viale Europa - Loc.
