The aim of this study was to determine the microbiological quality of three traditional smoked cooked meat products: kindziuk, smoked loin, and smoked ham, manufactured in north-eastern Poland. The total viable count (TVC) and presence of Salmonella spp., Escherichia coli, Staphylococcus aureus, and Listeria monocytogenes were determined. A total of 5 test series of 5 samples of each product (n = 75) were performed. The average TVC ranged from 2.96 log cfu/g to 6.36 log cfu/g, depending on the type of product and the test series. There were significant differences in the TVC in the samples of smoked meat produced at different periods of time by the same manufacturer (i.e. samples representing different production batches of the same product). These differences were most notable in kindziuk. None of the samples was positive for Salmonella spp., Escherichia coli, Staphylococcus aureus, or Listeria monocytogenes. Our results attest to a satisfactory microbiological quality of smoked meats and confirm consumers’ positive opinion about the health safety of traditional domestic meat products. Nevertheless, significant differences in bacterial contamination of samples from different production batches suggest that the manufacturers of this type of meat products should take steps to ensure a higher quality of their products.
The aim of this study was to evaluate the possibility of using PSE pork in the production of restructured hams. The raw material for hams consisted of muscles (m. semimembranosus) with a PSE defect, and the comparative material was high quality meat (RFN). The quality of the meat was assessed by measuring its pH, electrical conductivity, colour parameters, and drip loss during storage. The PSE and RFN meat was subsequently used for producing restructured hams. The evaluation of the quality of the hams included the evaluation of their texture, colour, chemical composition, and sensory properties (surface moisture, binding and juiciness). The cooking loss and the drip loss during storage were also determined. The PSE meat was characterized by lower pH, higher electrical conductivity, lighter colour, and considerably greater drip loss and weight loss after thawing compared to the RFN meat. The effect of the inferior quality of PSE meat on the quality of meat products can be limited by restructuring. Restructured hams made from the PSE meat were paler than those made from the RFN meat, but otherwise similar in quality.
