Impurities spread between
Cross-contaminated describes something that has been exposed to unwanted substances from another source.
In food safety, cross-contaminated surfaces or ingredients have picked up bacteria, allergens, or other contaminants through contact: The cutting board was cross-contaminated with raw chicken juice.
The term extends to any situation where materials mix unintentionally: The samples were cross-contaminated in the lab.
