SUMMARY— A relatively high percentage of apparently healthy pigs were Salmonella carriers and excreted salmonellae in the feces. Stress imposed by trucking did not significantly alter the excretion of salmonellae by the pigs. The incidence of salmonellae in fecal samples from 32 stress‐resistant and stress‐susceptible animals was investigated. There was a high incidence of salmonellae in cecum and colon contents, but salmonellae were not isolated from various muscles or from spleen, liver and kidney samples. Three of eight pigs were positive for Salmonella in the mesenteric lymph nodes. There was no apparent pattern of salmonella detection in regard to the stress‐susceptible condition of the animal.
