The purpose of this paper is to measure Mexicans’ perceptions and attitudes about the production and consumption of genetically modified organisms (GMOs).

A questionnaire with 63 questions that encompassed 11 latent factors was used to obtain information. The questionnaire was administered to 14,720 people in Mexico’s urban areas.

The results revealed important similarities and differences with studies in other countries, showing mainly that the respondents did not have sufficient information about GMOs, they have low level of knowledge about GMOs (31.28 percent), are highly distrustful of GMOs, perceive high risk regarding GMOs (59.13 percent), want transgenic products to be labeled (93.59 percent) and do not perceive GMOs’ social values and positive health effects beyond increasing agricultural productivity. Also, it was observed that the higher the educational level of individuals, the lower the acceptance of GMOs.

The authors conclude that it is necessary to generate and provide scientifically accurate information on GMOs, so that people are better informed and can give a critical opinion on the use of GMOs.

The major practical contribution of this research is that it provides empirical knowledge about the perceptions and attitudes toward the production and consumption of GMOs among the Mexican’s urban society, which can be of great help for the Mexican government to rethink if it is an appropriate moment to completely open the doors to international companies to cultivate crops like maize and others that have been postponed due to pressure from the environmental groups, farmers and other sectors of the society.

This is especially important in the context of maize as it is part of the cultural heritage of Mexico since ancient times. However, it is not clear what the overall perception is in the Mexican society on the use of GMOs for cultivation.

Southern regions of Mexico are the center of origin of several cultivated plants such as maize and legumes. The introduction of GMOs, called transgenics, in agriculture and food continues to cause enormous controversy in the perceptions and attitudes mainly among environmental groups and farmers in Mexico.
