English to Romanian Tech/Engineering Food & Drink

Toată fraza este:
People who have acquired botulism from contaminated food should be asked to give a history of everything they have eaten in the past five days before they became ill, especially canned or preserved foods.

Dacă s-ar traduce "canned" prin conservate, atunci "preserved"? Sau nu am nevoie de două cuvinte diferite, rămâne doar "canned or preserved foods" = "alimente conservate"?
Mulţumesc anticipat.
