In the wake of Japan's first case of mad cow disease, the Tokushima Prefectural Government on Sunday began to collect livestock feed, which might have used meat and bone meal (MBM) infected by mad cow disease, the government said.

According to the prefectural government, officials collected a total of 1.5 tons of livestock feed from four different agricultural cooperative in the prefecture.

MBM feed, a protein feed made from the crushed internal organs, skin and bones of cows, has been blamed for the spread of mad cow disease. Currently Japan bans the import of MBM from the European Union.

The officials will continue collecting feed today, and the collected livestock feed will be incinerated, they said.
