Fasciola hepatica is a parasite that causes on average 3.2 million in losses in the agricultural sector every year worldwide. It is a two-centimeter-long worm at adult size that mainly affects ruminants by means of water or raw vegetables that act as vehicles of infection. Moveover, in developing countries with deficient sanitary control systems, more than five million people have been infected. Though it does not have high death rates, it causes liver damage and makes the host more prone to catching other diseases.
