HOME FASCIOLIASIS TRANSMISSION SYMPTOMS TREATMENT PREVENTION
PREVENTION
Here are some simple steps to prevent transmission of F. hepatica and fascioliasis infection.
 |
The best way to prevent fascioliasis infection is to avoid eating water plants and drinking contaminated water. |
Specifically in the Bolivian Altiplano, the most commonly ingested plants that are contaminated are Nasturtium officinale (watercress), Juncus ebracteatus and algae of the Nostoc genus.
|
|
Water plants need to be properly washed with uncontaminated water before consumption. |
However this has been shown to only remove 50% of the metacerariae. Washing plants in vinegar, citric acid, or potassium permanganate solutions for ten minutes is more effective to completely remove metacerariae up to 100%. It should be emphasized that it would be best if these plants were not be eaten raw at all. If they are going to be eaten, water plants should be thoroughly cooked to kill any remaining parasites after washing. Dishes and utensils should also be properly cleaned after use with soap and non-contaminated water.
|
|
Improving sanitation practices will also help to decrease transmission of this pathogen. |
Indiscriminate defecation should be avoided and latrines should be built and used.
|
|
Clean, non-contaminated water should be used for drinking, washing food, cooking and cleaning plates and utensils. |
Water should always be boiled before using or protected, fresh water well should be drilled and used.
|
|
The grazing of livestock needs to be restricted in areas of fascioliasis. |
By restricting
the grazing of the livestock, we can prevent the animals from grazing or
defecating in or near water supplies. This will decrease the ingestion of
infected water plants by livestock and prevent further transmission.
