[2] A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. [2]
Common sources of chemical contamination can include: pesticides, herbicides, veterinary drugs, contamination from environmental sources (water, air or soil pollution), cross-contamination during food processing, migration from food packaging materials, [11] presence of natural toxins, or use of unapproved food additives and adulterants.

An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
Measurements to keep fruit from being cross-contaminated by viruses in the field and during processing. Measures to monitor and limit viruses in farm and facility workers who interact with the berries
When an unusual cluster of illness is noted, infection control teams undertake an investigation to determine whether there is a true disease outbreak, a pseudo-outbreak (a result of contamination within the diagnostic testing process), or just random fluctuation in the frequency of illness. If a true outbreak is discovered, infection control ...
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer.. Contaminated food . The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer).
