An incident of fraud in food production can change consumer behavior toward all brands that produce that kind of food, according to a new study.
The study, in which researchers tracked the impact of food fraud by an extra-virgin olive oil brand in Italy, shows that the value of products from the countries that produce olive oil declined, some by more than 50 percent.
“…there’s a negative spillover affecting all producers when consumers see this information…”
Syed Imran Ali Meerza, an agricultural economist at the University of Nebraska-Lincoln, says the study illustrates the need for better policing of the food industry in order to protect consumers and producers.
“We’ve shown there’s a negative spillover affecting all producers when consumers see this information,” Meerza says. “That has important policy implications because if there is negative activity going on in an industry, what should an industry do? This shows there needs to be a counteraction to that negative information.”
Food fraud, or the act of purposely altering, mislabeling, or tampering with any edible product, is a growing problem in global food supply chains. According to the US Congressional Research Service, there have been 60 percent as many incidents of food adulteration from 2011 to 2012 than had been identified in the 30 years between 1980 and 2010.
“Food fraud is nothing new, but the intensity and frequency have been on the rise,” Meerza says. “Globalization and a much more complex supply chain are contributors. It is also very difficult for consumers to judge the characteristics of the product.”
Research surrounding food fraud has largely focused on incidents and effects on consumers. The researchers say very little food fraud research has focused on producers’ reputations and livelihoods after an incident occurs. Their study is helping increase understanding of the impacts on producers and the industry itself.
For the study, researchers asked more than 100 consumers to put a value on different brands of extra-virgin olive oil. The brands were from Italy, Greece, and the United States. After reading an article about cases of food fraud involving Italian producers of olive oil, the consumers were asked again to place a value on each brand of EVOO.
The fraudulent action diminished the perceived value of all EVOOs by consumers. The value of Italian EVOO saw a 51 percent decrease in average valuation, consumers devalued the Greek EVOO by 13 percent, and United States EVOO’s value decreased by 9 percent.
Meerza is broadening this line of research and has been sought for his expertise by olive oil producers in the United States.
“They’re looking at labeling or certification that will increase trust in olive oil produced in the United States, and that’s based on what we found here,” Meerza says.
