Six major food manufacturers, including Nestle and PepsiCo, have been fined by the Brazilian Ministry of Justice for concealing the presence of GMOs in their products.

The companies are facing fines ranging from $277,400 to just over $1 million, amounting to $3 million in total, according to Telesur, who report:

The decision was reached as a result of an inspection carried out by Brazil’s Consumer Protection Agency Senacon in 2010, which found that GMOs had been used in cake mixes, snacks and various other products being sold in the country’s supermarkets.

Senacon accuse the companies of violating Brazilian consumer rights including the right to information, freedom of choice and the right for protection against abusive corporate practices.

Following the court ruling, Brazilian Institute of Consumer Defense researcher Ana Paula Bortoletto praised the decision for enforcing current legislation which requires the labeling of GMO products.

“The decision confirms the Ministry of Justice’s commitment to require all products that use genetically modified ingredients to include this information on their labels,” Ana Paula stated Thursday.

The sale of GMOs in Brazil were originally banned after the Institute of Consumer Defense won a lawsuit in 1998. However, in 2003 the Brazilian Ministry of Justice adopted measures that enabled the retail and use of GMO products, although a warning symbol is required for products intended for human consumption.
