Comparison of the microbiological and hygienic quality of turkey meat between six districts of the Kenitra city

Abstract

Meat is known to be one of the vehicles for many diseases to humans. The aim of this study is the comparison of the microbiological and hygienic quality of fresh turkey meat marketed in the most popular districts of Kenitra city. Fresh meat samples were taken from stores localized in six different districts. Microorganisms tests were conducted according to the appropriate standards. The Aerobic Mesophilic Flora (AFM) was most counted in district five (7.69±0.212 log10ufc/g), while the highest total and fecal coliform charges were obtained in district six with rates of 7.68±0.160 and 6.89±0.132 log10ufc/g, respectively. Cases of Salmonella spp were observed in all districts, except district five with frequencies up to 10.71%. Pseudomonas aeuroginosa charge was high in district five and its prevalence was high (21.42%) in districts two, four and six. Regarding Clostridium perfringens, the charges were up to 2.11±0.55 log10ufc/g in district six and a high prevalence of 42.85% was in district four. Escherichia coli showed dominance in all the districts studied with a high prevalence in district four with a rate of 75% and a high charge in district five (4.37 log10ufc/g). The presence of Staphylococcus aureus was significant in district four with a rate of 28.57% and a high concentration in district five (4.47 log10ufc/g). This study has shown great variability in the results found between the different districts and the rate of contaminations affecting this product. In fact, this microbiological and hygienic quality of raw turkey meat sold in these districts was judged marginal indicating the need for improved hygienic standards.

Differential Microbiological Quality on Marketed Frozen Turkey Breast and Thigh Meat

“…The obtained results in Staphylococcus aureus counts are consistent with Martínez-Laorden, et al [33], who found 2.52 log CFU/g. however, Jaber, et al [34] found a higher Staphylococcus aureus counts than our study. The results of this investigation showed that the mould and yeast were lower than those of Vural, et al [35], who reported an 88.18% rate.…”

A remarkable step in the aerobic biological treatment of Olive Mill Wastewater (OMW): A combination of selected microbial strains that enhance their decolorization and depollution

“…The enumeration of staphylococci is carried out on a selective Chapman medium. Cultures are incubated at 37 °C for 24 to 48 hours [44].…”

Chemical composition, organoleptic, physicochemical, and antibacterial properties of three plants of the lamiaceae family on Escherichia Coli strains

“…The antibacterial activity was evaluated against 78 strains of Escherichia coli isolated from turkey meat marketed at the point of sale, as previously studied [19].…”

“…The essential oil of each plant was tested to determine its antibacterial power using the disc diffusion method [18]. Petri dishes containing Mueller-Hinton agar medium were flooded with 1 ml of preculture of pathogenic bacteria.…”

“…These natural agents serve to reduce or replace chemical or synthetic preservatives that have detrimental effects on health [16,17]. In light of the foregoing, our study aims to evaluate the antibacterial effect of essential oils derived from three medicinal plants of the Lamiaceae family on 78 strains of Escherichia coli isolated from turkey meat marketed at the point of sale, which exhibit resistance to Gentamicin [18], to propose them as bioactive substances as alternatives to antibiotics and for poultry product preservation.…”
