| 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? 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. |

| Organic pig production provides an animal-friendly alternative to conventional production systems, but one of the concerns associated with the outdoor production form is an increased exposure to Salmonella and Campylobacter in the environment that potentially impairs the food safety of organic pork. The available data on Salmonella infections in organic pigs is scarce, but seroprevalence has indicated a higher occurrence of Salmonella in outdoor pigs. The potential beneficial effects of e.g. late weaning, low animal density and roughage with respect to resistance to Salmonella infections are discussed on basis of an experimental infection study. The persistence of Salmonella in a contaminated paddock environment constitutes a potential infection risk for... |

| A colony blot hybridization method with a digoxigenin-(DIG)labelled nucleotide probe was developed to enable Campylobacter jejuni species-specific identification of colonies present in minority. C. jejuni is the dominant cause of human cases of Campylobacteriosis. In contrast, C. coli is normally dominant in conventional pigs but it can be speculated that outdoor pigs host more C. jejuni due to a closer contact to the environment and wild-life where C. jejuni is pre-dominant. Since C. jejuni is considered more virulent to humans a potential shift towards C. jejuni in pigs may infer an importance to food safety. Individual pigs are often colonized with several Campylobacter strains. However, with conventional culturing techniques only few colonies are... |

| The prevalence of faecal Salmonella shedding has been compared in organic, conventional outdoor, and indoor finishing pig herds in a Danish survey with participation of 34 herds. Individual faecal and meat juice samples were collected from 30-50 pigs per herd and analysed for presence of Salmonella, and Salmonella antibodies, respectively. The results showed a low level of on-farm Salmonella shedding (<0,2 %) in organic and conventional outdoor herds compared to 2,5 % in indoor pigs (P<0,0001), and also a lower prevalence of Salmonella shedding in outdoor systems at slaughter (<2 %) compared to 4,1 % in indoor systems (P<0,01). The overall seroprevalence was 8,5 % with no significant differences between systems. Seropositivity was a significant... |

| According to the Council Regulation (EC) No 1804/1999), organic livestock production is intended to ensure quality production rather than maximising production. In organic pig production, the availability of limited amino acids is the first limiting factor and the main reason why the performance capacity is clearly diminished compared to conventional production. In order to compensate for the lower productivity, quality production is a conditio sine qua none. Possibilities to improve the quality of organic pork were investigated in different feeding trials. Results from a first trial in 1999 showed that diets based on organic cereals and home grown grain legumes (faba beans, peas and lupines) have the potential to produce pork with a high intramuscular fat... |

| Spread of antibiotic resistance (AR) along the food-chain is a major food safety concern due to the risk of treatment failure of human foodborne infections. Can lower AR levels be claimed as a particular quality of organic pork due to the restrictions on antibiotic usage? Or will the current slaughtering of organic and conventional pigs together abolish this quality attribute? Furthermore,lack of registration of antibiotic usage in some EU member states necessitates methods for estimating the consumption (control of imprudent use) of antibiotics in organic herds. |

| 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,... |

| There is only limited data available on the prevalence of zoonotic bacteria like Salmonella and Campylobacter specifically in organic pigs, but the increased exposure to these pathogens in the outdoor environment may influence the food safety of organic pork. However, the late weaning, low stocking density and roughage may help to increase the resistance to bacterial infections in organically reared pigs. Outdoor organic pigs were inoculated with Salmonella and mixed with Salmonella-free pigs to study the transmission between pigs. Following, the infection risk associated with the use of Salmonella-contaminated pastures was assessed by introducing new Salmonella-free pigs into the contaminated paddocks. Campylobacter is considered a natural part of... |

| In organic livestock production systems, farm-management factors are thought to play an important role in the on-farm prevalence of Toxoplasma gondii. Serological results and the results of an HACCP analysis were combined to determine important risk factors for the prevalence of this protozoan parasite. Mathematical analysis demonstrated that feeding goat whey to pigs and the presence of a high number of cats were positively correlated to T. gondii seroprevalence in pigs. Not covering roughage and the farmers' assumption that pigs can come into contact with cat feces also showed a positive relationship. In order to decrease the risk of T. gondii infecting their pigs, farmers should limit the access and number of cats on their farms and refrain from feeding... |

| 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... |

| For organic pig production little information is available about potential food safety problems with respect to zoonotic bacteria like salmonella. The aim of the current study was to examine the salmonella infection dynamics in organic pigs through an outdoor experimental set-up. Pigs inoculated with Salmonella Typhimurium were grouped with non-infected tracerpigs to determine the transmission of salmonella between animals. The results indicated that the organic pigs were perceptive to infections but that the susceptibility varied considerably between pigs. Furthermore, bacteriological examinations of soil and water samples from the pasture environment showed the ability of salmonella to survive in the non-host environment. Moreover, introduction of... |

| Carcass, meat, and fat quality were evaluated of 37 castrates of 4 different genotypes [Pi*Du*GLR (10), Pi*AS (7), Du (10), Du*GLR (10)] kept on grass clover and fed with coarse meal made up of farm grown cereal and grain legumes without optimising the amount of amino acids and their relation to the energy content. Due to the energy surplus in the diet and in relation to the diminishing muscularity of the genotypes (corresponding to the above-mentioned sequence) lean meat contents were on a low level whereas intramuscular fat contents increased distinctly. Sensory meat quality was only at a medium level and did not differ noticeably between the genotypes. It is concluded that adipose carcasses associated with increased intramuscular fat contents do not... |

| PURPOSE. Consumption of undercooked pork meat products has been considered a major risk factor for contracting toxoplasmosis in humans. Indoor farming and improved hygiene have drastically reduced Toxoplasma infections in pigs over the past decades. Whether introduction of animal-friendly production systems will lead to a reemergence of Toxoplasma infections in pigs is not yet known. Investigating this possibility was the purpose of this study. METHODS. Blood was obtained from pigs raised for slaughter and tested for Toxoplasma antibodies by using latex agglutination and indirect immunofluorescence testing, with confirmation by immunoblotting. RESULTS. None of the slaughter pigs (n = 621) from conventional farms (n = 30) were positive, whereas 38... |
