The objective of this work was to carry out a survey of the main causes of post-harvest losses in peppers, potatoes and onions marketed in the fairsand supermarkets of Santarém, Pará state. The work was conducted in the retail trade, in the following places: Supermarket, Cohab Fair, Old Airport Fair and Mercadão 2000. The damages in the vegetables were evaluated and classified in: physiological, microbiological and mechanical damages. In all the evaluated places all the vegetables presented some damage, that was attributed like responsible of the losses of direct or indirect form. On the onions the main damages were: thick stalk, poorly formed bulbs, flaccid, discolored and sprouted. All the evaluated peppers presented rectangular and green color, the main damages were: crushed, rotted, skinned, burned and attacked by insects, wounded, withered, cracked and poorly formed.
