Biogenic amine and microbiological profile of Serbian dry fermented sausages of artisanal and industrial origin and associated health risk

ABSTRACT

From the public health point of view, safety of dry fermented sausages is of concern due to possible presence of biogenic amines and some other food hazards. Taking into consideration that biogenic amines are chemical indicators of microbiological contamination, industrial and artisanal dry fermented sausages produced in Serbia were subjected to the microbiological and biogenic amine profiling. Microorganisms identified by MALDI-TOF MS included Cronobacter sakazakii and Listeria innocua, whereas the food pathogens were not detected. Biogenic amine content, determined by HPLC method in the range from 37.3 to 1186 mg/kg, was characterised as very low to low in 40% of the samples, moderate in 38%, high in 14% and very high in 8%. Risk assessment revealed that consumption of dry fermented sausages could cause histamine and tyramine intake up to 11.9% and 3.4% of threshold dose for healthy population, respectively. Adverse health effects would be rather unlikely for general population.
