On 23 December 2014, President Dilma Rousseff appointed Abreu as Minister of Agriculture, to serve during the president's second term, amid controversies among environmentalists, including the group Greenpeace. Abreu took office on January 1, 2015 during Rousseff's second inauguration. Abreu was fired in 12 May 2016, after president Rousseff was suspended by the Senate and vice-president Michel Temer was sworn as acting president, being replaced by Blairo Maggi.
On 23 November 2017 she was expelled from the Brasilian Democratic Movement Party because of her support of the opposition. In 2018 she joined the Democratic Labour Party and supported Ciro Gomes in his bid for presidency.
