Final answer:
The main difference between spicy salmon roll and spicy tuna roll lies in the fish used, with spicy salmon roll containing raw salmon and spicy tuna roll containing raw tuna. It's important to note the health risk associated with consuming raw fish, including the chance of parasitic infections such as those from Diphyllobothrium species, a concern previously observed with undercooked salmon.
Step-by-step explanation:
The difference between spicy salmon roll and spicy tuna roll primarily lies in the type of fish used to make these popular sushi items. Both rolls are typically made with sushi rice, nori (seaweed), and a spicy sauce combined with either salmon or tuna. The spicy salmon roll features raw salmon as its main ingredient, while the spicy tuna roll uses raw tuna.
It's important to be aware that consuming raw or undercooked fish, such as in spicy salmon and spicy tuna sushi rolls, can carry a risk of parasitic infections. One such parasite is the Diphyllobothrium species, also known as fish tapeworms. During the 1970s and early 1980s, undercooked salmon was linked to an increase in Diphyllobothrium infections in British Columbia. Although the reported cases of this parasitic infection are low in modern times, it is possible that not all cases are reported due to difficulties in identifying the causative agent.
