MADRID, November 22, 2010 (AFP) - Spain's main association of beef cattle producers (ASOPROVAC) on Monday called for an investigation into claims by Alberto Contador that contaminated meat was behind his positive doping test during the Tour de France.
The association said in a statement it had asked public prosecutors to open "a probe to clarify the possible truthfulness of the facts told by Alberto Contador."
It added: "Given that the cyclist has not made a formal complaint against public institutions -- the only way to trigger an official investigation that would definitively clear up this affair once and for all -- the association has decided to put the case in the hands of public prosecutor."
Contador emerged from this year's Tour de France with a third yellow jersey to add to his crowns from 2007 and 2009, bolstering his image as stage racing's man of the moment. Contador also won the Tours of Spain and Italy in 2008.
In September, however, the International Cycling Union (UCI) provisionally suspended the 27-year-old after trace amounts of clenbuterol, a banned weight loss/muscle-building drug that is also used to fatten cattle, were found in a urine sample taken on the three-week epic.
