This work is a continuation of the research published in the Revista CEJ, of the Brazilian Federal Court, in 2018, and presented at the II International Congress of Public Law: justice and the enforcement of human rights, held at the University of Coimbra/Portugal, in 2017. The labeling of transgenic foods is addressed as a means of guaranteeing full access to the Human Right to Adequate Food, in order to guarantee the promotion of Food and Nutritional Security to consumers. The current research aims to update the previous work, taking into account the context of worsening food insecurity rates in Brazil, especially in the post-Covid-19 pandemic period, and also taking into account the new resolutions of Anvisa that deal with food labeling, as well as the unarchiving, in the Federal Senate, of the Bill addressed in the previous research, known as “PL to end transgenic labeling”, seeking a critical approach to its possible effects. The essay uses the deductive method to compose a bibliographical research, using legislation, doctrine, jurisprudence and data contained in public and private information banks as sources.
