Routine water testing detected multiple contaminants that required immediate remediation.

The contaminative runoff from the factory poisoned the river's ecosystem.

She handled the samples contaminatively, which compromised the entire experiment.

Any contaminable surfaces in the facility must be sanitized after each use.

Food handlers must be trained to recognize and prevent cross-contaminations between raw and cooked foods.

If you use the same cutting board for raw chicken and vegetables, you might cross-contaminate the salad.

To prevent cross-contamination, wash your hands and sanitize surfaces between handling raw and cooked foods.

The lab implemented strict protocols to identify and isolate cross-contaminators before they could compromise experiments.

The salad was cross-contaminated when the same knife was used for raw chicken and vegetables.

The kitchen manager immediately disciplined the cross-contaminator who had spread peanut residue across the prep area.
