Abstract

Školjkaši predstavljaju opasnost za zdravlje ljudi zbog mogućnosti filtracije vode i akumulacije mikroorganizama. Bolesti se većinom javljaju nakon konzumacije sirovih ili nedovoljno kuhanih školjkaša, iako neki mikroorganizmi mogu ostati infektivni i nakon termičke obrade. Glavni izvor mikroorganizama u školjkašima su nepročišćene ili djelomično pročišćene otpadne vode. U ovom radu prikazane su karakteristike virusnih i bakterijskih patogena te bolesti koje oni uzrokuju. Od virusnih patogena opisani su virus hepatitisa A, norovirus i rotavirus, a od bakterijskih rodovi Salmonella, Shigella i Vibrio. Na kraju su navedene strategije prevencije bolesti koje uključuju prirodno pročišćavanje školjkaša u čistoj vodi, izgradnju boljeg sustava za pročišćavanje otpadnih voda, čestu kontrolu kvalitete školjkaša i edukaciju ljudi o mogućnosti zaraze i važnosti termičke obrade školjkaša.

Abstract (english)

Bivalves pose a threat to human health due to their ability of water filtration and accumulation of microorganisms. Diseases usually occur after consumption of raw or undercooked bivalves, although some microorganisms may remain infectious even after thermal treatment. The main source of microorganisms in bivalves is unprocessed or partially processed wastewater. This work presents the characteristics of viral and bacterial pathogens and the diseases they cause. Viral pathogens described in this work are hepatitis A virus, norovirus and rotavirus, while described bacterial pathogens are from the genus Salmonella, Shigella and Vibrio. At the end there is a list of strategies for disease prevention which include natural cleansing of bivalves in clean water, construction of a better wastewater treatment system, frequent quality control of bivalves and education of people about the possibility of infection as well as the importance of thermal treatment of bivalves.
