Fish is one of those love or hate kind of foods. The smell is especially pungent when it is raw, and the taste of the ocean even when it is cooked does not always appeal to everyone. That being said, sushi is a favorite of many people and it is considered quite healthy which makes it even more appealing. However, the key ingredient in most sushi, fish, can be of questionable quality. Do you actually know that you are eating salmon sashimi or could it be disguised as another fish?
A Canadian biology teacher named Dr. Jennifer McDonald from Fanshawe College decided she wanted her class to think critically about what is put in front of them. To add a fun edge, she decided that her students would take part in an experiment testing fish DNA with the fish from sushi restaurants being their test subjects. The experiment had some unexpected outcomes which she posted on her social media. In fact, they greatly surprised the residents of London, Ontario which is where the experiments were conducted and uncovered a fish fraud ring.
An active social media user, Dr. McDonald decided to document a class experiment involving fish DNA. She wanted her class to be able to positively identify different types of fish, which meant that they needed to collect samples from a variety of locations.
The biggest supplier of samples would be restaurants, specifically sushi ones. They regularly received new stock which meant her students just needed to eat out and grab a piece of fish for later.
