Why is an establishment number necessary on a pesticide label?

The establishment number on a pesticide label is crucial because it serves to trace the manufacturing facility in case of any issues that may arise with the product. This number is a unique identifier assigned by the Environmental Protection Agency (EPA) to each facility that produces, processes, or packages pesticides. In the event of a product recall or investigation due to safety concerns or adverse effects, having this establishment number allows regulatory agencies to quickly identify the source of the issue and take necessary actions to protect public health and the environment. This traceability helps ensure accountability and safety in pesticide use, thereby strengthening consumer protection.
