Since 1997, pig carcases produced tn Australian export abattoirs have been routinely monitored for Salmonella spp. and E. coli contamination using the standard USDA method (i.e. swabbing 3x 100cm2 areas on chilled p1g carcases). The National Salmonella carcase prevalence and serotype isolation frequency was calculated for the years from January 2000 to September 2006. The yearly prevalence range was from 1.19% (7/586) to 2.73% (28/1025) with a 7-year average of 1.88% (132/7038). The most frequent serotypes ISolated were Derby, Anatum, Havana, London, Agona and Adelaide. Overall S. Typhimurium was isolated in 5.3% (7/132) of the positive samples. For the same period for E. coli detection, overall 97.65% (21891/22417) of samples were below the Australian regulatory "m" desirable benchmark {1 cfu/cm2) , with a yearly range from 95.92% to 98.07% of sam?,les. Overall, only 0.08% (18/22417) of samples were >"M", the upper regulatory limit ( 1 02cfu/cm ).
