a
A total of 100 pigs were sampled at the postexsanguination step of processing and numbered sequentially. Both carcass and fecal samples were taken from pigs 40 to 100, resulting in matched samples. The 13 pigs listed are those swine that yielded both carcass and fecal isolates of Salmonella.
b
The numbers in parentheses refer to the number of isolates displaying each PFGE pattern for each sample.
