WHAT IS CHEMICAL CONTAMINATION?
HERE'S YOUR ANSWER.....
Chemical contaminants can enter the food chain from multiple sources. Contamination can occur during primary production from various environmental sources including:
- pollution.
- waste from factories.
- landfills.
- incinerators.
- fires.
- contaminated land, including from natural occurrence.
- contaminated water, for example, dioxins, halogenated organic compounds or heavy metals.
- plant diseases - mycotoxins.
- contamination from weeds, for example, plant toxins.
- carry over of certain substances from animal feed.
- climatic conditions, for example, wet conditions at key stages during growing and harvest can increase production of mycotoxins.
Chemical contaminants can also enter the food chain at the secondary production stage.
- during cooking and processing, for example, acrylamide, polycyclic aromatic hydrocarbons.
- storage, for example, mycotoxins.
- transportation and handling.
Chemical contaminants may be harmful to health at certain levels. It is necessary to manage their levels in food and reduce dietary exposure of consumers. Several measures are in place to manage the risk from these contaminants and reduce the levels at which they are present in food - including good practices and regulatory controls.
