International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Methicillin resistant Staphylococcus aureus has been known to be prevalent in the pig production for nearly 15 years now (Meemken et al., 2010). In 2008 a survey carried out in the EU determined a high prevalence of MRSA in herds of breeding pigs also in Germany (EFSA, 2010). Likewise, MRSA were identified in Germany in herds of fattening pigs (Alt et al., 2011), pigs at slaughter (Tenhagen et al., 2009), on carcasses (Beneke et al., 2011) and in meat from pigs at retail (BVL, 2013). The current investigation was carried out to determine the current prevalence of MRSA in herds ...

In Brazil, since 2011 clinical cases of salmonellosis has been increasing substantially. Nevertheless, few information is available about the antimicrobial profile, distribution, serotypes and genetic relationship among the strains. The objectives of this study were: to identify the Salmonella serotypes, to characterize the in vitro antimicrobial resistance profiles and to determine the genetic relationship of clinical isolates in Brazil. During 2016, clinical isolates of Salmonella (111) from nine States were sent to Embrapa Swine and Poultry for complementary analysis. First, isolates were serotyped by Kauffmann White Scheme. In parallel, the strains were tested against fifteen antimicrobials by disk diffusion method ...

Maternal Vaccination As An Effective Salmonella Reduction Strategy, Richard Piers Smith, Victor Andres, Francesca Martelli, Becky Gosling, Rob Davies

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella is a widespread pathogen that can infect a variety of animals, including man. Pork is considered, after eggs, the major source of infection in humans in the EU, with S. Typhimurium (ST), including monophasic strains (mST; S. 1,4,[5],12:i- and S. 1,4,12:i-) being frequently implicated. Reducing the prevalence of infected pigs on-farm contributes to minimising contamination of pig meat and edible offal for human consumption, as the slaughter process alone cannot cope with high levels of contamination. The persistent and frequently asymptomatic nature of porcine Salmonella infection, the organism’s colonisation of farm ...

Vaccination Against Lawsonia Intracellularis Decreases Shedding Of Salmonella Enterica Serovar Typhimurium In Co-Infected Pigs And Changes The Host Gut Microbiome, Fernando Leite, Connie Gebhart, Randall Singer, Richard Isaacson

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella enterica is a leading cause of foodborne illness in the world. Attribution studies have suggested pork as a major source for human salmonellosis in different countries (Mughini-Gras et al., 2013, Pires et al., 2014). In the United States, efforts to reduce the incidence of salmonellosis have mainly remained ineffective, the incidence of salmonellosis has not been reduced appreciably since 1996 (Boore et al., 2015). There is a consensus in the field that there is a lack of on farm cost-effective strategies to reduce the prevalence of salmonellosis (Dickson & Hurd, 2013). The source of S. enterica that contaminates pork products ...

Effect Of The Addition Of Protected Sodium Butyrate To The Feed On Salmonella Spp. Infection Dynamics In Fattening Pigs, A. Casanova-Higes, S. Andrés-Barranco, R. C. Mainar-Jaime

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The effectiveness of a new form of sodium butyrate protected with sodium salt of coconut fatty acid distillate for the control of Salmonella infection in fattening pigs was assessed. A dose of 3 kg/T of this product was added to the basal diet of a group of pigs for the whole fattening period while another group within the same fattening unit remained without treatment. A significant reduction in the number of infected pigs (4% vs. 61%; P<0.01) and in the median OD% values (19.4 vs. 55.9) at slaughter were observed in the pigs under treatment compared to the controls. Also, a significant association between high OD% values and Salmonella shedding and infection was detected. The use of this form of protected sodium butyrate may be useful to reduce Salmonella shedding and infection in slaughter pigs.

New Innovative Feeding Strategy For Reduction Of Salmonella In Swine, Janneke Allaart, Petra Roubos-Van Den Hil, Bart D'Heer, Coen Smits

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella sp. are a leading cause of gastro-intestinal disease in humans with tens of millions of human cases worldwide every year. Pork is an important food vehicle of Salmonellosis, resulting in fever, abdominal cramps, diarrhea, vomiting, and occasionally death. Reduction of Salmonella in the feed-to-food chain is key to reduce the number of human Salmonellosis cases. Furthermore, it has frequently been demonstrated that the use of antimicrobial agents in food animals favors the development of resistance among foodborne pathogens like Salmonella spp. Therefore, there is an urgent need for new antibacterial strategies to reduce Salmonellosis, since antimicrobial resistance is on ...

Taenia Solium Cysticercosis In The Unprocessed Pork Supply Chain In Nairobi And Environs, Kenya, James Akoko

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The zoonotic parasite, Taenia solium, is a serious public health threat in countries where it is endemic. The larval stage of this parasite is responsible for porcine cysticercosis and neurocysticercosis in humans, which is one of the leading causes of seizures and epilepsy in developing countries. While documented studies have only been conducted in western areas of Kenya, other areas, including Nairobi, have not been investigated to fully understand the epidemiology of the parasite. Seven hundred blood samples were collected from randomly selected pigs presented for slaughter at the largest porcine abattoir supplying unprocessed pork to butcheries within Nairobi city ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella is considered a major pathogen in Public Health. Córdoba is an important region for the production of pork. In this study we estimated the prevalence and risk factors associated with Salmonella at different stages of pig production chain (farms, slaughterhouses and pork sausages industries). The observed prevalence of farms in this study was higher than reported by EU. The main Risk Factors could be linked to the lack of good manufacturing practices in the whole pork chain in the region.

Escherichia Coli Resistance And Gut Microbiota Profile In Pigs Raised With Different Antimicrobial Administration In Feed, Caroline Pissetti, Jalusa Deon Kich, Heather K. Allen, Claudia Navarrete, Débora Da Cruz Payão Pellegrini, Nelson Morés, Marisa Cardoso

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Antimicrobials have been widely used in veterinary medicine for disease treatment, disease prevention, and growth promotion. Although, the mechanisms about in-feed additives use are still not completely understood, it is accepted that its use improves feed efficiency by reducing the microbial load in the intestinal tract, thereby reducing the pressure on the immune system and increasing energy availability for the animal. However, disruption to commensal bacterial communities by antibiotics in some cases can increase the gut colonization by pathogenic bacteria. In this sense, the aim of this study was to evaluate the Escherichia coli antibiotic resistance and the gut microbiota ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The wild boar (Sus scrofa), exotic invasive specie, is currently distributed in many Brazilian states, including Santa Catarina (SC) and Rio Grande do Sul (RS). Since the wild pigs are susceptible to zoonotic pathogens as Leptospira spp, Toxoplasma gondii and Brucella spp, their large populations, movements and dispersion can spread diseases, being a potential transmission source to humans, livestock and other sylvatic sympatric species. Despite its importance are there few information about sanitary status of this wild populations and their impact for human and livestock health in Brazil. Objective this work was to investigate the presence of antibodies to Brucella ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella enterica subspecies enterica is recognized as the etiological agent of Salmonellosis, a zoonotic disease transmitted in humans through contaminated food. In 2015, Salmonella s. p. was reported as the second bacterial agent responsible of gastro-enteritis in the European Union (EFSA, 2016). Pig consumption is considered as a major source of human Salmonella infections (Bonardi, 2017). Salmonella subspecies can be divided in 1530 serovars based on different epitopes and surfaces antigens. Associations exist between serovars and livestopchk species. In Pigs, in France, Salmonella Typhimurium, Derby and recently the monophasic variant of S. Typhimu-rium (vmST) are the most frequently isolated serovars ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Yersiniosis is a human disease mainly due to the ingestion of raw or undercooked pork meat contaminated mostly with Yersinia enterocolitica (Ye). In France, 74.3% of pig batches at slaughterhouses carried pathogenic Ye. Among them, biotype 4 (BT4) and biotype 3 (BT3) were often recovered. PFGE is one of the most used methods to type Ye, with the restriction enzymes, XbaI and NotI. Nevertheless, MLVA method based on the diversity of six loci tends to replace PFGE; this method showed a higher discriminatory power in others studies. We investigated the genetic diversity of Ye strains isolated in 2009 and ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The energy demand increase and recent new regulation for biomethane in Brazil have aroused new interests and perspectives for biogas from livestock wastes, especially swine manure. Brazil is the largest producer of animal protein and has perspective to keep growing in the next years, but to achieve this goal good practices of livestock waste management are required. The anaerobic digestion has become a common practice to treat the manure and also reduce production costs through energy recovery (Cherubini et al. 2015).


Alternatives To Antimicrobial Treatment In Weaners—The Veterinary Practitioner's Solution, Frede Keller Jan 2017

Alternatives To Antimicrobial Treatment In Weaners—The Veterinary Practitioner's Solution, Frede Keller

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

One way of lowering the need for antimicrobial treatment is to ensure that piglets are healthy and strong at weaning. This implies that the weaning weight should be 6-7 kg. Unfortunately, many piglets only weigh 3-5 kg at weaning, which predisposes them to disease including diarrhea, because they are not necessarily ready for a soy-based diet at weaning.

A Sudden Increase In Salmonella—How The Surveillance System Reacted: A Danish Experience, Vibeke Møgelmose, Lene Lund Lindegaard, Jan Dahl

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Denmark has had a serological surveillance of finisher herds since January 1995, and the current surveillance of Salmonella on carcasses has been in place since 2001. Both surveillances are parts of the Danish Action Plan for Salmonella in pigs and pork. Variations in the Salmonella prevalence are evaluated, and if a variation is exceptional, much effort is done to try to find the reason for the variation, to correct it and to learn from it.

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Hepatitis E is a zoonotic emerging disease distributed worldwide. The domestic swine and wild boars (Sus scrofa) are known as important reservoirs of HEV although HEV infections have been detected in other animal species. The southern region of Brazil has the largest swine productions in the country, ranging from highly-specialized commercial swine productions to small-scale non-commercial pig farms. The small-scale farms allow interactions between wild boars and domestic pigs, when occasionally pathogens transmission can occur between these populations. The aim of this study was to determine HEV seroprevalence in non-commercial domestic pigs and wild boars from two southern Brazilian states ...

A Study Of The Effect Of Movement Of Outdoor Pigs To A New Site On Salmonella Prevalence, Richard Piers Smith, Becky Gosling, Rob Davies

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Outdoor breeding of pigs in Great Britain constitutes a substantial proportion of the British pig industry, with at least 40% of the breeding herd kept outdoors. Outdoor production is viewed as more welfare friendly and forms a break between cereal crops. Outdoor pig production has a tendency for high Salmonella seroprevalence at slaughter, with evidence for a wide diversity of resident and transient infections on farm, often showing some overlap with local environmental and wildlife isolates. Outdoor pigs may be at increased risk of infection due to: the lack of a controlled environment that can be cleaned and disinfected between ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Meat consumption is frequently associated with foodborne diseases. The onset of such occurrences may be due to failures on animal health surveillance or during meat processing. Many efforts are made in the industry to minimize any kind of meat contamination which can affect human health. Salmonella has an important role in the public health and economy, once it is recognized as one of the most important zoonosis (Valero et al., 2014). In Brazil, 90% of reported cases involving foodborne pathogens, in which the pathogens were identified, from 2007 to 2016, were caused by Salmonella spp. (Brazil, 2016).

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

In this study, we assess whether on-farm serology may be useful for predicting Salmonella shedding at slaughter. Serology on serum samples collected 60 and 90 on fattening and three days before slaughter predicted somewhat shedding at slaughter with no significant differences among them. Pigs with higher OD% values at these point times would have higher risk of shedding when arriving to slaughter. On-farm serology may help to predict to some extent the risk of Salmonella shedding at slaughter in seropositive fattening units, which may allow for prompt on-farm and slaughter interventions to mitigate the risk of shedding when pigs arrive ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The use of antibiotics in livestock production is very common and widespread. The reason for their use can be very diverse. Examples are the treatment of clinically sick animals, the improvement of growth performance, as well as the prevention of common bacterial infections. However, the extensive use of such antimicrobials raised concerns of increasing the incidence of resistant pathogenic bacteria, which has a negative impact not only on livestock production, but also on human health. In the last years, many different substances have been investigated as suitable alternatives to the use of antibiotics as growth promoting agents and as prophylactic ...
