Trichinellosis: old facts and new developments

Verh K Acad Geneeskd Belg. 2002;64(4):233-48; discussion 249-50.


Trichinellosis is a helminth zoonosis, which is known since long, but which is emerging or re-emerging in several regions of the world. During the last years the number of cases of trichinellosis in pigs and man in several East-European countries has increased very much due to the breakdown of the veterinary services because of the difficult political and socio-economic situation. In several third world countries on the other hand trichinellosis has become more important due to the increasing number of small traditional pig farms, in which the hygienic conditions are suboptimal. Furthermore, outbreaks of human trichinellosis have been reported due to recently discovered new species such as T. pseudospiralis and T. papuae. Over the last 25 years horsemeat has been more important as a source of human trichinellosis within the European Union than pork or wild boar meat. In Belgium, however, no cases of human trichinellosis have been reported since 1979. A review is presented of the available data on animal trichinellosis in Belgium. The potential risk for the consumer is discussed. Finally, some suggestions are made for a new approach of trichinellosis control in Belgium and the European Union.
