Abstract Background In the absence of legal maximum limits for a chemical hazard in food, the competent authority may act if high contamination levels that endanger public health are identified. A pragmatic approach to identify whether a value is potentially too high, is to set action levels which, if exceeded, call for action involving a notification, withdrawal of the food from the market, legal measures or an investigation. Scope and approach As control policy's action levels should be considered as part of risk management, which is not always based on scientific risk assessment alone, the concept of an ‘estimated acceptable concentration’ (EAC) is introduced. The EAC is defined as a risk-based level of a substance in a food below which the exposure to the substance via the food does not pose a concern or a risk for public health. This EAC concept is substantiated by a quick scoping review of scientific literature and reports. Key findings and conclusions Case-dependent, whether a threshold effect level can be defined or not, the EAC can be calculated based on the health-based guidance value or the margin of exposure (MOE) approach. The EAC can serve as a basis for an enforceable or food safety management action level, allowing food inspectors to take uniform actions and providing clarity to food business operators. Application of an EAC or action level should be viewed in the appropriate framework, including consideration of the acceptable risk level and uncertainties related to toxic potency and exposure assessment.
