Miguel Herrera bans beef for Mexico's players ahead ahead of World Cup
Brazil's Group A opponents at the World Cup, Mexico, have banned their players from eating beef before and during the tournament for fear of failing drugs tests due to stimulants sometimes found in the meat.
Head coach Miguel Herrera will take no chances after several of his squad were cleared in 2011 of taking clenbuterol, a substance sometimes found in livestock to make it leaner.
"Given what happened, we have decided not to eat red meat," Herrera told a news conference, "Here there's very good cooking and we have a spectacular chef."
"We've also been telling players for the last month and a half not to eat beef and they've paid heed."
The extreme measures imposed by Herrera also include a ban on sex during the competition as Mexico attempt to reach the last 16 of the World Cup for the sixth consecutive time, stretching back to 1990.
