In the context of globalization and industrialization,food safety issues have increasingly become an important factor affecting public health and social stability.The complexity of the food supply chain increases the sources and management difficulties of food safety risks.Harmful substances such as microorganisms,chemical pollutants,and heavy metals in food may enter the human body through various pathways,posing a threat to health.Therefore,scientific food safety risk assessment and response strategies are crucial for ensuring food safety at all stages from production to consumption.This paper aims to analyze the causes of food safety risks,assessment methods,and explore effective countermeasures.
