What is trichinosis?
Trichinosis or trichinellosis is a parasitic disease caused by larvae and adult parasites of nematodes of the genus Trichinella spp, which affects humans, domestic and wild mammals, birds and reptiles.
It is a zoonosis, which is transmitted by humans, unintentionally, by consuming meat or meat derivatives, raw or poorly cooked, that contain live muscle worms.
In our country, trichinosis is widely distributed, the main source of human infection is the domestic pig, although there are others, such as wild boar or puma. In general, outbreaks have been linked to pigs with poor sanitary breeding conditions and a lack of slaughter control.
The way trichinosis manifests itself in the form of outbreaks in humans and in the form of a focus in pigs, and the lack of specific treatment for infection in the cystic phase (encapsulation), makes it necessary for health and sanitation. animal services. take steps to intervene in outbreaks with the greatest urgency possible. Early treatment of exposed people is important to reduce the possibility of developing severe forms of the disease.
On the other hand, the confiscation and destruction of potentially contaminated pork or food products is necessary to prevent the risk of the general population becoming ill.
