Fig. 2.11-5. Salmon<br />

drying on the Yukon<br />

River. Indigenious<br />

peoples of the Arctic<br />

rely on nutrient dense<br />

traditional foods<br />

such as fish, marine<br />

mammals, wild game<br />

and plants to provide<br />

them with food<br />

security and nutrition.<br />

Fig. 2.11-6. Walrus<br />

meat may be infected<br />

with Trichinella<br />

nativa which causes<br />

Trichinellosis, a<br />

disease caused by a<br />

roundworm whose<br />

larvae encapsulate<br />

in the muscle tissue.<br />

Illness can occur in<br />

humans, who ingest<br />

infected undercooked<br />

or raw meat, and it<br />

can range from mild<br />

or inapparent to a<br />

fulminating fatal<br />

disease depending on<br />

the number of larvae<br />

ingested. Trichinella<br />

nativa (shown right,<br />

x 100 magnification)<br />

can survive in frozen<br />

muscle tissue for<br />

many years.<br />
