Abstract

Thirty five samples of locally made beef burger were obtained from markets in Tripoli city and different microbial counts were performed as an index for microbial quality. The total mesophiles count was >108 cfu/g, while the total psychrotrophes count was >10' cfu/g. Tested samples contained enterococci and total staphylococci was >107 cfu/g (17% of the samples contained >10 cfu/g of Staphylococcus aureus). Moreover, >10³ MPN/g of coliforms were found in all samples. On the other hand, yeast was >107 cfu/g while only 60% of the samples contained mould >10' cfu/g. Thus all of the tested samples contained high number of microbial contaminants exceeded the suggested Libyan standard specifications for beef burger. Public health importance as well as factors that may limit such high microbial counts in beef burger were discussed.
