Resumo
The demand for safe food has been an increasing market. The absence of
pathogenic microorganisms, especially those that cause zoonotic disease in
animal products, is a requirement of national and international. Among these
microorganisms, Salmonella has been a concern during the year, industry and
poultry products has gained importance also in the production of pigs. From the
increasing emphasis on safety of meat products that reach the consumer, has
been encouraged to identify ways to reduce or eliminate Salmonella sp., before
slaughter, since the reductiun of infection rates to the pre-slaughter results in
increased safety of pork products (FUNK, et al., 2001). In pig production, the
salmonella is characterized by two problems: the presence of serovars
pathogenic adapted to pigs, which cause gastroenteritis and sepsis and the
presence of strains that do not cause disease in animals, but are major sources
of contamination of carcasses in abattoirs and that can infect humans
(zoonosis). Salmonellosis is a major human foodborne diseases varying in
severity according to patient conditions. Children, elderly and
immunocompromised are at highest risk (SOBESTIANSKY & BARCELLOS,
2007). The epidemiology of Salmonella infection in pigs is complex, with
multiple factors involved in transmission of the microorganism. Along the
production chain is possible to observe the amplification of the problem, usually
by the rapid transmission of bacteria to uninfected animals, after contact with
environment and animals positive for Salmonella. The prevalence of Salmonella
sp. can be measured by serological and bacteriological (VAN DER GAAG et al.,
2004), and the microbiological isolation is the most widely used method of
diagnosis. The security of a free product of Salmonella passes through the
control measures implemented on the farm, in transport, expects pre-slaughter
and processing line. Only an integrated effort at all stages ensure the success
of control programs. This review aims to address issues related to salmonellosis
in intensive system of rearing pigs, describing the epidemiology, pathogenesis,
diagnosis, and suggest control measures.
