During a recent workshop on environmental protection in seafood processing, it was found that small-scale processing facilities in Hai Phong City, Vietnam face the risk of pollution due to their simple processes, lack of equipment, and inadequate waste collection and treatment measures. Similarly, in Thanh Hoa Province, some seafood processing facilities located in residential areas contribute to environmental pollution due to poor compliance with environmental protection laws and lack of investment in treatment works. To address these issues, it is recommended to relocate polluting production facilities out of residential areas and focus on controlling aquatic breed production facilities, improving infrastructure, and implementing specific solutions to encourage businesses to prioritize environmental protection.
