Can the restricted use of antibiotics in organic pig farming be documented to provide a safer, high quality meat product with less antibiotic resistant bacteria? Organic Eprints
Åbo, S.; Jensen, A.N..
The project SafeOrganic aims to document that the restricted use of antimicrobials in organic pig production leads to lower levels of antibiotic resistant bacteria compared with the level in conventional pigs. However, the project will also address the risk of losing this quality parameter, due to a widespread practice of slaughtering organic pigs together with conventional pigs, implying a risk of cross-contamination.

Development of real-time PCR and hybridization methods for detection and identification of thermophilic Campylobacter spp. in pig faecal samples Organic Eprints
Jensen, A.N.; Andersen, M.T.; Dalsgaard, A.; Baggesen, D.L.; Nielsen, E.M..
Aims: To develop a real-time (rt) PCR for species differentiation of thermophilic Campylobacter and to develop a method for assessing co-colonization of pigs by Campylobacter spp. Methods and results: The specificity of a developed 5’nuclease rt-PCR for species-specific identification of C. jejuni, C. coli, C. lari, C. upsaliensis and of a hipO gene nucleotide probe for detection of C. jejuni by colony-blot hybridization were determined by testing a total of 75 reference strains of Campylobacter spp. and related organisms. The rt-PCR method allowed species-specific detection of Campylobacter spp. in naturally infected pig faecal samples after an enrichment step, whereas the hybridization approach enhanced the specific isolation of C. jejuni (present in...

High diversity of salmonella serotypes found in an experiment with outdoor pigs Organic Eprints
Jensen, A.N.; Lodal, J.; Baggesen, D.L..
Little is known about the risk of Salmonella infection in outdoor pig production, but seroprevalence data has indicated a higher occurrence of Salmonella in outdoor production systems than in conventional indoor systems. This is perhaps due to the increased exposure to the surrounding environment including contact with wildlife. An unexpected high diversity of Salmonella serotypes, as e.g. S. Uganda and S. Goldcoast, which are not normally isolated from pigs, was detected in connection with an experimental study on transmission of Salmonella in outdoor organic pigs. In order to elucidate the potential source of the different Salmonella serotypes, a small-scale examination of wildlife was performed. Salmonella was not detected in any of a total of 22 rats,...

PathOrganic – Risks and Recommendations Regarding Human Pathogens in Organic Vegetable Production Chains Organic Eprints
Arthurson, V.; Baggesen, D.; Brankatschk, K.; Dalsgaard, A.; Duffy, B.; Fenzl, C.; Friedel, J.K.; Hackl, E.; Hartmann, A.; Hedin, F.; Hofmann, A.; Jäderlund, L.; Jansson, J.; Jensen, A.N.; Koller, M.; Mäder, P.; Rinnofner, T.; Schmid, M.; Storm, C.; van Bruggen, A.H.C.; Widmer, F.; Wyss, G.S.; Zijlstra, C.A.; Sessitsch, A..
PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens in plant produce. The project evaluates whether organic production poses a risk on food safety, taking into consideration sources of pathogen transmission (e.g. animal manure). The project also explores whether organic versus conventional production practices may reduce the risk of pathogen manifestation. In Europe, vegetable-linked outbreaks are not well investigated. A conceptual model together with novel sampling strategies and specifically adjusted methods provides the basis for large-scale surveys of organically grown plant produce in five European countries. Critical control points are...

Reducing the risk of food borne pathogens (Campylobacter) in pre-slaughter pigs via short-time feeding with prebiotics Organic Eprints
Jensen, A.N.; Hansen, L.L.; Baggesen, D.L..
Reducing the presence of human pathogens like Campylobacter and Salmonella (zoonoses) in their animal hosts is important to enhance food safety of products of animal origin. Campylobacter is considered to be a commensal in the gastrointestinal tract of pigs due to its typically high prevalence. Consequently, it is difficult to control Campylobacter in pigs at farm level by usual hygienic measures, especially in open systems of organic pig production (Jensen et al 2006). However, another potential means to control pathogens is inclusion of non-digestible oligosaccharides (prebiotics) in the diet. For example, prebiotics proofed successful in control of the intestinal disease swine dysentery caused by the spirochaete Brachyspira hyodysenteriae (Molbak et al....

Salmonella bakterier kan spredes blandt økologiske grise Organic Eprints
Jensen, A.N.; Baggesen, D.L..
Forsøg har vist, at Salmonella bakterier kan overføres fra smittede økogrise til salmonella-frie grise holdt på udendørs arealer. Desuden kan salmonellabakterier overleve i foldmiljøet og under visse betingelser smitte salmonella-frie grise, som senere indsættes i folden. Overaskende blev der fundet flere forskellige typer af salmonellabakterier i både grisene og i foldmiljøet i løbet af forsøgsperioden.

Salmonella og Campylobacter i økologisk svineproduktion Organic Eprints
Jensen, A.N.; Baggesen, D.L..
De mere ekstensive systemer i økologisk svineproduktion formodes at have en positiv effekt på dyrenes robusthed f.eks. over for infektioner. Der er dog ingen dokumentation for, at økologiske svin har et lavere indhold af de almindelige zoonotiske bakterier som f.eks. Salmonella og Campylobacter end konventionelle svin. Et forsøg med økologiske smågrise viste, at salmonellainfektioner kan overføres både mellem grisene men også via et salmonellasmittet miljø. Graden af den smitte grisene udsættes for synes væsentlig for etablering af en infektion. Campylobacter, som anses for at være en naturlig del af grisens tarmflora, blev fundet i alle smågrisene. Desuden var det muligt at påvise både den typisk svineassocierede Campylobacter art C. coli og arten C....

Salmonellatyper i forsøg med økogrise Organic Eprints
Jensen, A.N..
Imod forventning blev der fundet en række forskellige salmonellatyper i et forsøg med udendørs økologiske grise på forsøgsgård. I konventionelle danske svinebesætninger med salmonellainfektioner ser man nemlig oftest kun én eller evt. få typer af salmonella samtidigt. Udendørs grise kan nemt tænkes at være udsat for en større smitterisiko end indendørs grise, da salmonellabakterier generelt har et bredt værtsspektrum og derfor vil kunne forekomme i den vilde fauna og i miljøet. Men salmonella blev ikke fundet i indfangne mus, rotter og kragefugle, og dyrene var dermed ikke umiddelbart kilden til de forskellige salmonellatyper.

Slagterier giver bakterier til økosvin Organic Eprints
Jensen, A.N.; Aabo, S..
Økologiske grise indeholder færre antibiotikaresistente colibakterier end konventionelle grise, viser ny europæisk forskning. Men forskellen risikerer at bliver udlignet i slagteprocessen. Spredning af antibiotikaresistente bakterier er generelt bekymrende, fordi den i sidste ende kan betyde, at alvorlige sygdomme hos dyr og mennesker ikke kan behandles. Den årlige overvågning af resistens i danske svinebesætninger målt med E. coli som indikatorbakterie viser, at 28-42 pct. af de testede bakterier er resistente over for de fem antibiotikatyper, hvor der oftest ses resistens. Men der er brug for mere viden om spredning af de resistente bakterier. I det fælleseuropæiske forskningsprojekt SafeOrganic har vi derfor undersøgt og sammenlignet forekomsten...

Survival and transmission of Salmonella enterica serovar Typhimurium in an outdoor organic pig farming environment Organic Eprints
Jensen, A.N.; Dalsgaard, A.; Stockmarr, A.; Nielsen, E.M.; Baggesen, D.L..
It was investigated how organic rearing conditions influence the Salmonella enterica infection dynamics in pigs and whether Salmonella persists in the paddock environment. Pigs inoculated with S. enterica serovar Typhimurium were grouped with Salmonella-negative tracer pigs. Bacteriological and serological testing indicated that organic pigs were susceptible to Salmonella infections, as 26 of 46 (56%) tracer pigs turned culture positive. An intermittent and mainly low-level excretion of Salmonella (<100 cells per g partly explains why the bacteriological prevalence appeared lower than the seroprevalence. Salmonella persisted in the paddock environment, as Salmonella was isolated from 46% of soil and water samples (n = 294). After removal of pigs,...

The occurrence and characterization of Campylobacter jejuni and C. coli in organic pigs and their outdoor environment Organic Eprints
Jensen, A.N.; Dalsgaard, A.; Baggesen, D.L.; Nielsen, E.M..
The occurrence and species distribution of thermophilic Campylobacter was investigated in organic outdoor pigs. An increased exposure of outdoor pigs to C. jejuni from the environment may cause a shift from a normal dominance of C. coli to more C. jejuni, which may imply a concern of reduced food safety. Bacteriological methods for determination of Campylobacter excretion level were combined with colony-blot hybridization and real-time PCR for specific detection of C. jejuni in pigs. Campylobacter was isolated from pigs (n = 47), paddock environment (n = 126) and wildlife (n = 44), identified to species by real-time PCR and sub-typed by serotyping (Penner) and pulse-field gel electrophorsis (PFGE) genotyping. All pigs excreted Campylobacter (103–107 CFU...
