Food Microbiologist and Associate Professor Julian Cox from the UNSW School of Chemical Engineering said the little-known practice of food fraud not only tarnished consumer trust but also posed a food safety risk.
"Consumers are left in the dark when producers substitute ingredients that could potentially cause adverse health reactions," he said.
"Whether it's buying honey or olive oil at the supermarket or going to a high-end restaurant and ordering expensive wagyu steak, as consumers, we expect to get what we pay for. It's hard, or even impossible, for the consumer to know what is real and what is fake."
"And typically, we don't question the product we're buying because we put trust in something as fundamental as the food supply chain," Associate Professor Cox added.
Speaking of the supply chain, the increased globalisation of imports and exports, and various geopolitical and environmental factors are sadly creating more opportunities for food fraudsters to "get away with it."
"You can pick almost any commodity, any food or beverage, and you can almost guarantee that products within that category have been tampered with somewhere along the supply chain - even if it's in the labelling and claiming to be from a specific region of the world," Associate Professor Cox says.
So is there anything consumers can do to ensure they don't fall victim to food fraud?
According to Associate Professor Cox, it's easier said than done.
"Unless you're a true expert in that area, you're probably not going to tell if the local fish and chip shop has sold you barramundi or if they've just sold you battered shark meat."
He does suggest however that early detection and prevention methods such as authenticity testing, or government intervention could go a long way in solving this global problem.
"It's always in the best interest of the farmers and food distributors themselves to make sure consumers are getting what they're paying for," he says.
"These measures can help protect the integrity of the industry and thus ensure the food quality and safety is not compromised."
