| Ascaris suum and Ascaridia galli, the large round worm of pigs and poultry, respectively, persist even in intensive management systems, where a high level of hygiene is practiced. It is necessary to control these helminths to minimize production losses and improve animal welfare. Commercial disinfectants are commonly used to clean pens in conventional pig and poultry farms but their efficacy against the thick-shelled nematode eggs has not been sufficiently documented. However, it might be difficult to control these parasites because of their complex thick-shelled eggs, which can resist harsh environmental conditions. Commonly used disinfectants such as Virkon S®, FL-des GA® typically claim efficacy against viruses, bacteria and some fungi, but very few... |

| Ascaris suum is the most common intestinal worm in pigs irrespective of production system. However, organic farms which promote animal welfare (e.g. by providing pastures and bedding material) may further promote survival of the eggs through which the parasite is dispersed to new hosts. The parasite has a negative effect on production results and possibly impairs vaccines. A one year survey of 5 Danish organic farms therefore aimed at mapping the occurrence of parasite eggs in the farm environment, supplemented with laboratory and field studies, including serial necropsies of different age groups of pigs from 2 farms to monitor infection levels. The combined results showed that eggs were present on farrowing and weaning pastures, ensuring continuous... |

| The transmission of Ascaris suum depends upon the type of swine production system. Organic farm with outdoor facilities provide favorable conditions for the development and survival of this soil transmitted helminth. The present study was carried out from late October 2013 to late February 2014 to study the infection dynamics of A. suum in pigs born and raised on two Danish organic. |
