Abstract

Result indicated that the quadratic model with a correlation coefficient (R²) of 0.9376 was significantly predicted the responses (p<0.05). RSM model showed that optimal condition refers to 0.50 ppm ozone for 20 min, resulting in 100% decontamination of Opisthorchis viverrini metacercariae (OVMC). These findings demonstrated the high efficiency and practical applicability of ozone-based treatment as a food safety intervention to reduce opisthorchiasis transmission through cyprinid fish, with potential impact on public health in endemic regions.
