Greenpeace [...] lodged a bid with the CSIRO for all documents relating to nutritional testing the science body had conducted, or intended to conduct, on pigs, rats or humans on foods produced by genetically modified organisms. Last week, the CSIRO’s freedom of information officer rejected the bid, saying she had identified 1042 documents relating to the request. The officer estimated it would take one person 539 hours to process them, which was an ”unreasonable” diversion of resources and not in the public interest.
