NASA has asked to suspend the sale of lunar dust that was fed to cockroaches for the sake of experiment

Dust collected during the Apollo 11 mission in 1969 was given to insects to eat to determine if it contained pathogens. Cockroaches fed on moon dust were then studied at the University of Minnesota by entomologist Marion Brooks. According to the results of her research, she did not find any negative effects of insects eating moon dust. The dust was fed to cockroaches to check whether the regolith contained some kind of "lunar plague" dangerous to humanity.
