Giving evidence at a Senate hearing, veterinary scientist Fed- erico Infascelli described experiments in which he had apparently showed harmful effects in animals that were fed GM crops. Cattaneo spent the weekend poring over his papers. She could not understand the data, and discussions with Infascelli did not help. So she prompted investiga- CISCA CASTELIJNS/NATURE IN STOCK/FLPA CISCA CASTELIJNS/NATURE tions into his work, which eventually saw some of the papers retracted. Her team went on to produce a 1,556-page docu- ment for the Senate compiling nearly all available scientific evidence about GM crop safety. For her pains, Cattaneo was demonized by some in the Senate as a lob- byist for the agricultural biotechnology firm Monsanto.
