Salmonella contamination of feed (I): importance

Feed is one of the risk factors in the epidemiology of salmonellosis and therefore, control of pathogens in the feed should continue to be considered an essential component of any control program for swine salmonellosis.

Salmonellosis in finishing pigs in Spain: prevalence, antimicrobial agent susceptibilities, and risk factor analysis

A herd-based survey of Salmonella in pigs was carried in a major pig producing region of Spain. Mesenteric lymph nodes were collected from the carcasses of 25 pigs from each of 80 herds at time of slaughter.

Abstract

Use of an avirulent live Salmonella Choleraesuis vaccine to reduce the prevalence of Salmonella carrier pigs at slaughter

The results indicate that administration of a Salmonella choleraesuis-attenuated vaccine on the first day of life decreases Salmonella isolation and seroprevalence in pigs at slaughter.

EFSA: factors associated with Salmonella pen positivity

A European Union-wide baseline survey on Salmonella in holdings with breeding pigs was carried out in 2008. Now EFSA publishes the results from analyses of the associations of 19 pen- or holding- level factors and Salmonella positivity of pens in holdings with breeding pigs. Also the results from correlation analyses between Salmonella prevalence in breeding and in production holdings, from analyses of the Salmonella serovar distribution across the European Union, and from analyses of an additional within-holding prevalence study carried out by five Member States are also presented.

European Union - Report on antimicrobial resistance in zoonotic bacteria affecting humans, animals and food

Compiled by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC), the report indicates that resistance to antimicrobials was observed in zoonotic bacteria, such as Salmonella and Campylobacter, which may cause infectious diseases transmissible between animals and humans and which can be found in foods.

Abstract

Survey of Salmonella populations from swine waste-treatment technologies

The objectives of this field survey were to evaluate the effects of several promising swine waste-management and treatment technologies on reducing Salmonella presence and populations and to characterize the diversity of Salmonella isolates recovered from the waste streams using serotyping and antibiotic-susceptibility analysis.

Effect of probiotic-, bacteriophage-, or organic acid-supplemented feeds or fermented soybean meal on the growth performance, acute-phase response, and bacterial shedding of grower pigs challenged with Salmonella enterica serotype Typhimurium

Lactobacillus plantarum, microencapsulated organic acids or fermented soybean meal may be taken into account as antimicrobial alternatives for piglet diets.

Abstract

Antimicrobial resistance, virulence-associated genes, and pulsed-field gel electrophoresis profiles of Salmonella enterica subsp. enterica serovar Typhimurium isolated from piglets with diarrhea in Korea.

Salmonella enterica subsp. enterica serovar Typhimurium was isolated from diarrheic piglets in 2 periods, 2000–2001 (n = 25) and 2005–2006 (n = 17). To compare the characteristics of the isolates collected during the 2 periods, all isolates were tested for antimicrobial resistance, the presence of virulence genes, and pulsed-field gel electrophoresis (PFGE) patterns.

United Kingdom - VLA publishes the Salmonella in Livestock Production report for 2009

A total of 5,334 pig submissions were received by VLA/SAC during 2009, down from 5,761 in 2008 and 6,176 in 2007. Diagnostic pig submissions however (which generate the bulk of Salmonella incidents in pigs) actually rose by a fifth from 1,490 in 2008 to 1,797 during 2009.
