A.Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.
Explanation:
The text explains that the disease was identified in 1986. Seven years later, in 1993, the disease had reached an epidemic level and was causing huge losses to the farmers and panic among the consumers.
In 1997, governments banned some food for the bovines and the epidemic was quickly controlled afterwards. By 2010, the disease had largely disappeared.
The farmers are angry that the governments didn't help them earlier and the consumers are angry they were put at risk.
