Abstract
The prevalence and incidence of TBC, TSC, TMC, Salmonella spp., and Listeria spp in the examined meat products. Isolation and identification of L. monocytogenes, S. aureus and Salmonella spp. from the examined meat products.Identification the antibiotic resistance in the obtained isolates of L. monocytogenes. The intensity of biofilm production in L. monocytogenes obtained from different meat products.
Ensuring food safety and strict hygienic practices adopted across the meat industry’s whole supply chain is a primary responsibility of the food safety sector. Monitoring the sanitary status of the retailed meat products is necessary to complete this task. Meat products including luncheon, sausage, burger, and minced meat retailed in Sharkia governorate, Egypt, were evaluated for hygiene indicators such as total bacterial counts (TBC), total coliforms count (TCC), total Staphylococcus aureus (TSC), and total mold counts (TMC). Furthermore, isolation of some pathogenic microorganisms such as Salmonella spp., and Listeria spp., was done.
The results of the investigation indicated that every sample examined comprised mesophilic bacteria. Upon performing the calculation of the total bacterial count (TBC) in log10 cfu/g for the obtained samples, the mean TBC values for the examined luncheon, burger, sausage and minced meat samples were determined to be 5.72±0.25, 5.24±0.36, 5.60±0.28, and 5.83±0.35 log10 cfu/g, respectively. The minced meat samples had a greater TBC content than the other samples examined..
The total coliform counts of the meat products under investigation were assessed. The data collected unequivocally indicated that minced meat samples contained the highest counts of coliforms in comparison to the other meat products. Coliform bacteria serve as notable indicators of microbiological hygiene, underscoring the criticality of upholding sanitation throughout the entirety of the process of handling and preparing meat and meat products. The findings gathered indicated that the meat products under investigation contained coliform bacteria.
