AT the APHA Meeting of the EpidemiPkology and Occupational Health Sections in 1965. some of the problems and questions relating to Salmonella excretion in market swine were reviewed and presented.' A number of workers over a period of years observed that when swine were examined on the farm, the Salmonella infection rate, as measured by rectal swabs, was low. However, if swine were similarly examined in holding pens at the slaughterhouse, or by cecal or rectal swabs taken after slaughter, the observed infection rate was often from 30 to 80 per cent.2-6 Proposed explanations of these findings fall into two groups:read more

Identification and quantification of risk factors in animal management and transport regarding Salmonella spp. in pigs
TL;DR: It is concluded that the farm-phase forms the core of all current problems, and that better prevention and control can be achieved by, very strict and consistent farm hygiene in combination with promotion of the colonization resistance of animals kept together with a prudent use of broad spectrum antibiotics.

Salmonella enterica Infections in Market Swine with and without Transport and Holding
TL;DR: This study demonstrates that rapid infection during transport, and particularly during holding, is a major reason for increased S. enterica prevalence in swine.

TL;DR: It is concluded that food animals are a major source of antimicrobial-resistant salmonella infections in humans and that these infections are associated with antimicrobial use on farms.

Gastrointestinal microbial ecology and the safety of our food supply as related to Salmonella.
TL;DR: Approaches to reducing Salmonella in animals must take into consideration that the microbial ecology of the animal is a critical factor that should be accounted for when designing intervention strategies, and it is vital to understand how they function so that the law of unintended consequences is not invoked.
Journal ArticleDOI
The effect of lairage on Salmonella isolation from market swine.
TL;DR: It is suggested that pigs became internally contaminated with Salmonella after leaving the farm, possibly while in the abattoir holding pens, and that 18 h lairage, in clean facilities, does not increase shedding.
