MacNeish and Eubanks (2000) reject the AMS radiocarbon dates on maize from the Tehuacán Valley, claiming that the specimens were contaminated with a substance called Bedacryl. We do not believe that the dated fragments were contaminated, and we review the processes by which they were selected and analyzed. We also describe Bedacryl and conclude that, had it been present as a contaminant, the resulting 14C ages should have been older rather than younger than expected. Considered along with recent AMS dates on cultigens from Tamaulipas, it seems evident that post-depositional disturbances in rock-shelter sites sometimes caused mixing of older and younger objects. Direct AMS radiocarbon dating is currently the best and least destructive way to determine whether or not an individual plant specimen is the same age as seemingly associated wood charcoal
