Ensuring a negligible risk of Trichinella in pig farming from a control perspective

摘要

Today, the majority of pigs are raised in industrialised pig production systems with a high level of biosecurity resulting in a negligible risk of Trichinella. Carcass testing therefore seems less relevant if the aim of testing is to protect public health. However, traditional pig production (including backyard production) still occurs, and organic pig production is on the increase in some areas, suggesting a continued need for carcass testing from such compartments. These diverse developments within pig production have changed the epidemiologic situation of Trichinella. This has necessitated an adaption of the legislation regarding Trichinella surveillance and control, in order to ensure and document public health while also allowing trade of livestock and meat without unnecessary restrictions. This is reflected in the recent development of the international legislation regarding Trichinella and associated control obligations for trade in pork as described in the EU legislation and by OIE/FAO/Codex.
