Investigation of microbial association of traditionally fermented sausages

The investigation included fermented sausages produced in the countries of west and south-east Europe, Greece, Bosnia and Herzegovina, Croatia, Hungary, Italy and Serbia. The sausages were produced in local meat industries in a traditional way without the use of starter cultures. Samples were collected from three production batches on day 0 and again after 2, 4, 7, 14 and 28 days. Microbiological analyses included the principal ingredients (meat, fat tissue), casings and additives (sugar, mixture of spices, salt), and the finished products. From all batches of fermented sausages from each individual country, 150 strains of lactic acid bacteria and 150 strains of coagulase-negative cooci were isolated. Biochemical characteristics of the isolated microorganisms were determined by API system (bioMerieux), i.e. by API 50 CHL and API Staph. Identification of all strains was made using the computer program APILAB Plus. From the hygienic standpoint, it is highly important that Listeria monocytogenes, Salmonella spp. and Staphylococcus aureus were not found in the finished product. During all stages of investigation, lactobacilli and staphylococci prevailed.
