Abstract;Within a relatively short period after Bovine Spongiform Encephalopathy (BSE) screening test employing the Enzyme-linked Immunosorbent Assay was implemented in Japanese meat-inspection centers on October 18, 2001, we were able to examine 140 head of cattle per day. This was possible because of such instrument improvements as a modified medical spoon and a small, zippered sample bag for collecting brain stems. Of the 36,870 head we had treated by the end of December, 2002, 81 were subjected to retests. All retested samples, including a specimen further subjected to a confirmation test, turned out to be negative. In addition, we classified the cattle by species, sex, and age and compared optical densities (OD) among the groups. The OD values of old cows were found to be slightly, but significantly, higher than those of younger animals (P<0.05). (author abst.)
