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.

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

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

When raw chicken touches the salad bowl, it cross-contaminates the vegetables and poses a health risk.

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