QUADRAM_AC_UK 29/10/20 A bacterial virus helped the spread of a new Salmonella strain (ST34) - Researchers at the Quadram Institute have implicated a toxin-carrying virus in the emergence of a new strain of Salmonella in pigs. Salmonella is associated with a large number of cases of foodborne infection resulting in diarrhoea and in some cases severe complications.
Half of all Salmonella infections in the European Union are linked to pigs, and a new strain called ST34 is dominant in this livestock animal. ST34 has now spread in pig populations worldwide and is pandemic. New strains are known to have emerged repeatedly since surveillance records began over 60 years ago. The ST34 strain is a type of Salmonella called Typhimurium, which accounts for a quarter of all Salmonella infections.
In the UK over half of all Typhimurium infections are now caused by the ST34 strain. Unlike a related Salmonella called Enteritidis that has been largely controlled in layer hen flocks in the UK, little headway has been made in intervening years to control Salmonella Typhimurium.

PATHOGENS 29/01/19 Non-typhoidal Salmonella in the Pig Production Chain: A Comprehensive Analysis of Its Impact on Human Health. Salmonellosis remains one of the most frequent foodborne zoonosis, constituting a worldwide major public health concern.
The most frequent sources of human infections are food products of animal origin, being pork meat one of the most relevant. Currently, particular pig food production well-adapted and persistent Salmonella enterica serotypes (e.g., Salmonella Typhimurium, Salmonella 1,4,,12:i:-, Salmonella Derby and Salmonella Rissen) are frequently reported associated with human infections in diverse industrialized countries. The dissemination of those clinically-relevant Salmonella serotypes/clones has been related to the intensification of pig production chain and to an increase in the international trade of pigs and pork meat. Those changes that occurred over the years along the food chain may act as food chain drivers leading to new problems and challenges, compromising the successful control of Salmonella.

Abstract In seven EC swine abattoirs Salmonella prevalence (ISO 6579/2002) and serotypes of 25 piglets, 61 finishing pigs (lymph nodes, colon content, carcass and liver surface) and slaughterhouse environments (scalding water, surfaces in contact with meat and not in contact with meat) were investigated.

ITALIAN JOURNAL OF FOOD SAFETY - 2016 - Influence of pigskin on Salmonella contamination of pig carcasses and cutting lines in an Italian slaughterhouse. Abstract Ninety pig carcasses and twenty one food contact surfaces (FCSs) were tested for Salmonella in a slaughterhouse processing ca. 380 pigs/h between 2014-2015.
Sampling was performed during seven sessions. Four carcass sites of 100 cm2 each (back, belly, jowl externally, and the diaphragmatic area internally) were swabbed after evisceration. Meat conveyors and dressing tables were tested swabbing areas of 200 to 400 cm2. After pre-enrichment in buffered peptone water, samples were tested by Salmonella MDS® assay and the presumptive positives were confirmed by the ISO 6579 method.

The shedding patterns of Salmonella spp. and MLVA profiles of Salmonella enterica subspecies enterica (I) serotype 1,4,,12:i:- were monitored in a 12-month longitudinal observational study of five pig herds to inform management; provide indications of potential hazard load at slaughter; and assist evaluation of MLVA for use by animal and public health practitioners.
Twenty pooled faecal samples, stratified by age group, were collected quarterly. When Salmonella was cultured, multiple colonies were characterized by serotyping and where S. Typhimurium-like serovars were confirmed, isolates were further characterized by phage typing and multiple locus variable number tandem repeat analysis (MLVA).

FRONTIERS IN MICROBIOLOGY 06/01/17 Addressing Antimicrobial Resistance: An Overview of Priority Actions to Prevent Suboptimal Antimicrobial Use in Food-Animal Production.
Introduction Since the discovery of sulfonamides in 1932, antimicrobials have been used across the human and animal health sectors to cure infectious diseases. The global rising demand for animal protein for human feeding will potentially lead to a massive increase in AMU in food-animal production, estimated to rise by 67% between 2010 and 2030. However, because of differences between national regulatory frameworks surrounding antimicrobial sales, there are only limited data regarding AMU, particularly in low- and middle- incomes countries (Van Boeckel et al., 2015). In 2012, 26 European Union countries’ average consumption of antimicrobials was respectively 116.4 and 144.0 milligrams per kilogram of estimated biomass in humans and animals (European Centre for Disease Prevention, and Control [ECDC]/European Food Safety Authority [EFSA]/European Medicines Agenc [EMA], 2015).
Yet, these results hide large differences among species, administration route and classes. FIGURE 1. Regulations.

Summary Aims: The objective of this study was to establish critical temperature limits to prevent cross-contamination of pork carcasses during scalding.
Methods and Results: Mixtures of antibiotic-resistant mutants of Salmonella species were heat treated at 50, 55 and 60°C in samples of commercial scald tank water. Surviving cell numbers were estimated by plating treated suspensions on (i) tryptone soya agar (TSA) and (ii) on TSA, overlaid with brilliant green agar plus nalidixic acid and streptomycin sulphate and used to estimate D-values for the treated mixed cell suspensions.
Conclusions: A time–temperature combination of 1·4 min at 60°C is required to achieve a 1 log reduction in Salmonella in scald tank water. The predicted equivalent at 65°C is 0·18 min.

Cross-sectional studies in breeding and fattening pigs revealed more or less important prevalences in countries with high production and a strong export industry (EFSA, 2008, 2009) (Figure 1A and 1B). However, the control plans, which should have begun in 2012, have still not been implemented in most European countries today. PIGSITE 25/11/16 Salmonella Reduction in Pork Production.
