South African Consumers’ Knowledge Of Genetically Modified (Gm) Food Products And Influences That Affect The Purchasing Decision Of Gm Foods

Prevailing food insecurity has necessitated the leveraging of alternative food products if the Sustainable Development Goal 2 (SDG2), referring to zero hunger for the worldwide population, is to be achieved. Although the production of genetically modified (GM) plant-based crops has been adopted in South Africa (SA), and available for human consumption, a dearth of research exists in respect of SA consumers’ knowledge of, and the influences that affect the purchase of GM food products. An exploratory survey study design included 326 consumers, purposefully selected through snowball sampling from Mooi river, in KwaZulu-Natal province, SA. Exploratory Factor Analysis (EFA) was used to identify underlying drivers for the knowledge and influences on the purchase decisions of GM food products. It was found that although respondents were aware of GM food products and understood the meaning of “genetically modified”, they lacked general knowledge about GM food products, reflected in the minimal scope of their knowledge and uncertainty of GM components present in food products as identified through an EFA. Consideration for purchasing would include the potential to increase food supplies, the reduced usage of pesticides, carcinogenic effects, allergenicity, harmful effect on the environment, longer shelf life and the unnatural development of GM food products. Through EFA, consumption and production implications, consumer advantages, product identification elements, and agricultural pesticide practices were underlying drivers of the influencers of consumers’ GM food product purchasing decisions. Food insecurity could persist if GM consumer education is not re-introduced in SA to address consumer apathy and sense of disengagement towards GM food products. This is attributed to the limited consumer knowledge about GM food products. This study has contributed towards a better understanding of the current consumer perspective on GM food products and what it will take to turn the GM food product aversion into informed consumer decisions and practices. Future research in SA is needed to determine the demographic profile of consumers and how that will influence GM food product purchases in the wake of addressing food security.
