Another type of food borne illness that could occur after consuming tainted sashimi is Diphyllobothriasis. This disease is an infection within the intestines that occurs when the tapeworm "Diphyllobothrium latum" is consumed. Common fish such as trout, salmon, pike, and sea bass harbor this parasitic larvae in their muscles. Due to the innovation of the chilled transport system paired with the salmon and trout consumption, an increasing number of cases have been recorded annually in northern Japan due to the spread of this disease.
