Microbiological Analysis of Traditional Sausage in Prishtina, Republic of Kosovo, During Production and Storage

Traditional sausage in the Republic of Kosovo has been produced for centuries as a traditional method of preserving the nutritional value of meat. In sausage fermentation, natural microbiota such as lactic acid bacteria (LAB) and Micrococcaceae usually participate; these are not only critical for ensuring product safety and flavor development but also represent significant biotechnological potential. The purpose of this study was to analyze traditional fermented sausage, in terms of production practices and hygiene, throughout the production and storage phases. Samples in three stages of production and maturation were analyzed for microbiota, pH, and water activity level. Our results show that the main changes in the bacterial populations from 0 to 7 days of storage included increases in the total numbers of viable mesophilic aerobic bacteria (LAB) and Micrococcaceae (MC). However, the Enterobacteriaceae and coliforms (EC) count showed a significant decrease (p < 0.05) in 1.60 ± 1.62 lg cfu/g by day 14. In conclusion, the number of EC in the traditional sausage was decreased during storage, while LAB and MC were stable, data that indicate the safety and quality of this product. No differences regarding the production practices and storage of traditional sausage were observed, based on the data from the butchers who participated in this study.
