Michael Hansen, senior scientist at Consumers Union said, “Before this, the longest study had only lasted nearly eight months”(Sacramento). The study involved two-hundred rats and spanned over two years, the average life expectancy of the rats used. The researchers investigated how eating Monsanto’s Roundup-Ready corn affected rats’ health. They separated rats into 10 groups: Three had part of their standard diet replaced at varying levels with Roundup-Ready corn that had been treated with Roundup in the field; three received the same feed protocol, but with untreated Roundup-Ready corn; three ate no GM corn but had tiny amounts of Roundup herbicide in their drinking water; and one control group ate two-thirds standard rat chow and one-third non-GM corn. Each group contained ten males and ten females. The researchers say their results show “severe adverse health effects, including mammary tumors and kidney and liver damage, leading to premature death” from Roundup-Ready corn and Roundup herbicide, whether they were consumed separately or together. Almost all of the ill effects manifested after ninety days. By the end of the study, fifty to eighty percent of the females had developed large tumors, compared with thirty percent developing tumors in the control group.
