Riots

South Koreans are rioting to prevent US beef from entering their food supply.

SEOUL, June 30 (Reuters) - South Korean police said on Monday they have detained more than 100 people for violence at weekend rallies against a U.S. beef import deal, with tensions expected to rise this week when the product returns to stores.[...]
South Korea and U.S trade officials said about a week ago they had reworked a beef import deal first struck in April which sparked mass street protests, caused Lee's support rate to plummet and led to a crisis for his four-month-old government.

Last week, South Korea started processing the first batch of U.S. beef to enter the country under new quarantine rules designed to allay Korean fears of mad cow disease by limiting imports to beef from younger cattle and prohibiting risky parts.

Older cattle are considered more at risk of the disease.
