In a piglet producing farm severe disease occurred in weaner pigs two weeks after weaning. Clinical symptoms were acute and peracute cases of death and a high prevalence of wasting piglets. By microbiological examination oedema disease was diagnosed to be the cause of disease. In addition, an insufficient biosecurity on farm was assessed. Shigatoxin-producing E. coli (STEC) were detected in a water pipe providing drinking water for one pen. Recommended changes in biosecurity and hygiene measures were implemented only insufficiently. No further cases of death occurred in a group of piglets after vaccination with Ecoporc Shiga (R) and treatment with colistin sulfate/zinc oxide, but prevalence of wasting piglets remained high. The bad economic situation of the swine market at that time and forthcoming retirement of the farmer led to the farmer's decision to give up piglet production. This case report highlights a potential impact of water hygiene in the development of oedema disease. In general, further characterization of environmental microorganisms could provide arguments to achieve compliance of the farmer for implementation of hygiene and management measures on farm.
