stressor
A change in conditions, such as a drought, pest or chemical exposure, which often has negative effects on an organism or population
In food safety, a stressor is any factor that can cause harm or stress to humans, animals, or the environment. This can include chemical substances (like contaminants or pesticides), biological agents (like bacteria or viruses), physical factors (like temperature or radiation), or even nutritional imbalances.
EFSA uses the concept of stressors to identify and evaluate potential hazards in the food chain. By studying how different stressors affect health or safety, EFSA can assess risks, set safety limits, and provide scientific advice to help manage or reduce exposure, ensuring food and feed are safe for consumers and animals. EFSA has also extensively evaluated stressors that affect pollinators, such as honeybees, including the impacts of pesticides, pathogens, and nutritional deficiencies, helping to protect bee health and maintain ecosystem services.
