Abstract:
In the years 2000-2001 eighty nine portions (445 samples) of minced meat (beef and pork, beef, pork, veal, turkey) produced by supermarkets and other meat producers from Łódź and around Łódź were examined to check if they meet the standard requirements of PN-97/A-82009 and PN-97/A-82009/A1. The following parameters were determined according to PN-94/A-82055: the total number of microorganisms, most probable number of Escherichia coli, enumeration of Staphylococcus aureus and detection of Salmonella. In addition the presence of Listeria was determined in 25 g of examined meat. The examination showed that 36 (40.4%) portions of minced meat did not meet the requirements of standards mainly because the number of most probable number of E. coli exceeded the norm values.
