Although the ingredients of LBAM-F have been published on the CDFA website, the ingredients of OLR-F and the concentrations of the different components and residues from the chemical manufacturing process—necessary to determine toxicity levels during applications—remain unpublished.[15] Many question the statements by state officials that the products used for the aerial spray, Checkmate OLR-F and Checkmate LBAM-F, are safe to be sprayed on densely populated residential areas. At an April city council meeting in the city of Alameda California, Councilmember Frank Matarresse asked CDFA Secretary Kawamura, "If this were sprayed on an open field, would farmworkers be allowed to be in the field while you are spraying?" Secretary Kawamura responded with "No."[16]
