A Study about Microbiological Quality and Species Identification of Frozen Turkey Meat

Abstract

Abstract:The aim of this study was to identify potential health risks and evaluate the microbiological quality of frozen turkey meat sold in Diyarbakır, Turkey. In this study, a total of 110 frozen turkey meat samples were collected from retail markets in the city of Diyarbakır. The samples were analyzed by using standard analysis methods for total mesophilic aerobe bacteria, coliform bacteria, Escherichia coli, Staphylococcus-Micrococcus spp., Yersinia enterocolitica, sulfite reducing anaerobe bacteria, mould&yeast, Salmonella spp. and Listeria monocytogenes. Detection of meat species samples were determined by ELISA. The mean counts of microorganism in the frozen turkey meat which were analyzed, total mesophilic aerobe bacteria were found as 9.5x10 6 cfu/g, coliform bacteria as 2.7x10 4 cfu/g, Escherichia coli as 1.1x10 3 cfu/g, Staphylococcus-Micrococcus spp. as 3.4x10 4 cfu/g, Yersinia enterocolitica as 3.3x10 4 cfu/g, sulfite reducing anaerobe bacteria as 4.5x10 1 cfu/g, mould&yeast as 2.2x10 4 cfu/g. The existence of Salmonella spp, and Listeria monocytogenes in the examined samples were found as 3.63% and 17.27%, respectively. All samples analyzed were found to be turkey meat. In conclusion, this study demonstrates that some pathogens, including Salmonella spp., L. monocytogenes, E. coli and Yersinia enterocolitica are present in frozen turkey meat. Also, the presence of these organisms indicated that there were poor hygienic conditions during the slaughtering, packaging, storage and sales process. Therefore, this food is a serious risk to the public health. Temperature control also is a key issue in producing frozen turkey meat. In addition, it is also important that the products must be manufactured under good hygienic practices.

Microbiological quality evaluation of aerobic and vacuum packed broiler chicken carcass under different frozen temperature storage

“…The incidence of mould contamination of frozen chicken meat-cuts and giblets distributed in Zagazig city, Egypt [13] . The obtained results revealed that frozen gizzards had significantly higher TMC followed by frozen livers, breast and thigh and the mean (log cfu/g) values in such samples were 3.60, 3.47, 3.17, 2.69 respectively and the results of yeast and mould count of the samples are in accordance with the findings of various authors [11][12][13] .…”

“…In the present study the yeast and mould count are within the limits of Food Safety and Standard Authority of India. The microbiological quality of frozen turkey meat sold in commercial outlets of Diyarbakır, Turkey and reported an average value of 2.2x10 4 cfu/g for yeast and mould count [12] . The incidence of mould contamination of frozen chicken meat-cuts and giblets distributed in Zagazig city, Egypt [13] .…”

“…Our results are less than those obtained by Díaz-Jiménez, et al [36] (84%), Patyal, et al [37] (68%), Jaber, et al [5] (67.8%) and Abdellah, et al [38] (83%). Our result was largely higher than that found by Vural, et al [35] (39.09%) and Iroha, et a. […”

“…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.…”
