What is the significance of the EPA Establishment Number?

The EPA Establishment Number is significant because it identifies the specific production facility where a pesticide is manufactured. This number is crucial for regulatory purposes, as it allows the Environmental Protection Agency (EPA) and other authorities to track the production and ensure compliance with safety and environmental standards. By associating a product with its manufacturing location, the EPA can more effectively monitor and address any issues related to pesticide safety, quality control, or potential contamination.

Each establishment that produces a pesticide is assigned a unique number, making it easier to trace back any concerns or adverse effects reported from the use of the pesticide to its source. This traceability is vital for maintaining public safety and accountability within the pesticide industry.

The other options do not correctly represent the function of the EPA Establishment Number. Active ingredients, expiration dates, and retail prices are different aspects of pesticide information that do not pertain to the identification of the manufacturing facility.
