Will ducks get sick if they eat apple snails?
The apple snail has strong adaptability, high reproductive capacity and fast growth speed. It is an intermediate host of Echinostoma revolutum and Angiostrongylus cantonensis, and has become a worldwide invasive alien species that poses a great threat to human health. So will ducks get sick if they eat apple snails? Let's take a look together!
I. Will ducks get sick if they eat apple snails?
Ducks will not get sick if they eat clean apple snail meat. However, apple snails that grow in water bodies containing parasites carry parasites, and feeding them raw to ducks can cause the ducks to become infected with tapeworms, flukes and other parasites. It is best to cook the apple snails or dry them in the sun before feeding them to ducks.
II. Dietary taboos for apple snails
Apple snails can be infected with Angiostrongylus cantonensis and other parasites, so they must be thoroughly cooked before eating. They must never be eaten raw or half-cooked, especially cold-dressed snail meat or grilled snails, which must not be eaten. The outbreak of angiostrongyliasis in Beijing in 2006 was caused by people eating undercooked apple snails.
III. The harm caused by apple snails
The apple snail is native to the Amazon River basin in South America. After being introduced by humans to Taiwan, China, some parts of southern China and Southeast Asian countries, the apple snail lost the constraints of its original natural enemies. Rice seedlings are its preferred host plant, and the climatic conditions are very favorable for its growth and reproduction, thus causing serious harm to rice production in these areas.
April to June and August to October each year are the peak periods for apple snail egg-laying and hatching, and also the peak period when adult snails and older juvenile snails cause concentrated damage. Rice, Chinese milk vetch, arrowhead, water chestnut, sweet potato, vegetables and other crops are the main targets of damage by apple snails, with damage to rice being especially serious. Apple snails can cause damage throughout almost the entire growth period of rice, with the main damage period being from the seedling stage to the tillering stage. Juvenile and adult snails bite and feed on rice leaves and tillers, reducing tillering and thus the number of effective panicles, resulting in reduced yield.
Apple snails may also become carriers of diseases and parasites. Improper cooking methods, or eating them raw or undercooked, can pose a threat to human health. For example, the Metastrongylus carried by them can cause fatal eosinophilic meningitis, and the flukes they carry can cause skin allergies. The shells of apple snails are sharp and can easily cut farmers' hands and feet, and their large amount of feces can pollute water bodies. Competition with native species leads to a reduction or even disappearance of local freshwater organisms, affecting aquatic biodiversity.
