One in six Taiwanese people suffered from foodborne illness annually during a four year period studied by researchers.
From 2012 to 2015, almost 3.9 million foodborne illnesses and 50 deaths occurred annually in the country.
Scientists said the study, published in the Journal of the Formosan Medical Association, provided the first national estimates on the disease burden from foodborne illnesses in Taiwan.
Among just more than half of foodborne illnesses cases with identifiable causal microorganisms, non-typhoid Salmonella, norovirus, and Vibrio parahaemolyticus were leading pathogens.
Foodborne illnesses caused a substantial financial disease burden, with a medical cost up to NT $1.3 billion (U.S. $43,400) annually.
