At the garbage dump on Piyungan, Bantul, Jogjakarta, there are many cows and goat stroll around and eat the trash. Based on the observation, organic and non-organic trashes in the landfill become the main menu of those animals everyday. Edi Suryadi, the lecturer of the faculty of Animal Husbandry in Gadjah Mada University said to the people that they don’t need to buy any cow which was farmed in the dirty environment because those animals might be contaminated by diseases.
