Abstract
A study was conducted to compare the excision sampling technique used by the export
market and the sampling technique preferred by European countries, namely the biotrace
cattle and swine test. The measuring unit for the excision sampling was grams (g) and square
centimetres (cm2) for the swabbing technique. The two techniques were compared after a pilot
test was conducted on spiked approved beef carcasses (n = 12) that statistically proved the
two measuring units correlated. The two sampling techniques were conducted on the same
game carcasses (n = 13) and analyses performed for aerobic plate count (APC), Escherichia
coli and Staphylococcus aureus, for both techniques. A more representative result was obtained
by swabbing and no damage was caused to the carcass. Conversely, the excision technique
yielded fewer organisms and caused minor damage to the carcass. The recovery ratio from
the sampling technique improved 5.4 times for APC, 108.0 times for E. coli and 3.4 times for
S. aureus over the results obtained from the excision technique. It was concluded that the
sampling methods of excision and swabbing can be used to obtain bacterial profiles from both
export and local carcasses and could be used to indicate whether game carcasses intended for
the local market are possibly on par with game carcasses intended for the export market and
therefore safe for human consumption.
