On July 29, 2020, the United States Environmental Protection Agency, Region IX ( EPA ) conducted a For Cause virtual inspection by video conference at the Adelanto ICE Processing Center ( Adelanto ) located in Adelanto, California. The inspection was in response to complaints from detainees that a registered pesticide, HDQ Neutral (EPA Registration Number 10324-155-5741), was being used in a manner that led to illness symptoms in detainees. Failure to follow pesticide label directions is a violation of the Federal Insecticide, Fungicide, and Rodenticide Act ( FIFRA ). The investigation uncovered a number of FIFRA violations.
