Abstract

Background: This study aimed to investigate chemical and microbiological properties of 1260 meat product samples, including sausage, bologna, hotdog, Kebab, and hamburger, in Hamadan, Iran from 2012 to 2015. Materials & Methods: All microbial (total viable count as well as, Coliform, Salmonella, Escherichia coli, Staphylococcus aureus, Clostridium perfringens, mold, and yeast counts) and chemical (pH as well as salt, phosphate, sodium nitrite, moisture, protein, total fat, starch, nitrite, nitrate, and ash contents) properties were assessed by AOAC method. Findings: Microbial tests on sausage and bologna samples showed that the total count of microorganisms was higher (37.3%) than the national standard limit. In 11.3% of Kebab samples, the number of yeasts and molds was higher than the national standard limits. Also, in 3.5 and 17.07% of hamburger samples, the total count of microorganisms as well as the number of molds and yeasts were higher than the national standard limits, respectively. In 34.6% of bolognas, 15.9% of sausages, 3.8% of hamburgers, and 54.3% of hotdogs, the moisture content was above the national standard. The fat content was above the national standard in 34.7% of sausages, 1.4% of Kebabs, 9.8% of bolognas, 1.2% of hamburgers, and 6.5% of hotdogs. Conclusion: The present study results showed that the level of contamination of a considerable number of samples was not matched with national standards, which could be a major health risk for consumers. © 2021, TMU Press.
