			Contamination refers to the presence of an unwanted constituent, impurity, or infectious agent in a material, physical body, natural environment, workplace, etc. It can occur in various forms and contexts, including biological, chemical, and physical contamination.

	Contamination can occur through a variety of sources. These can include [[chemicals]], [[bacteria]], [[viruses]], [[radiation]], and [[metals]]. These contaminants can enter the environment through various means such as industrial processes, agricultural practices, waste disposal, and accidents.		==Types of Contamination==

	== ~~Types of~~ Contamination ==		===Biological Contamination===
			Biological contamination involves the presence of harmful microorganisms such as bacteria, viruses, fungi, or parasites. This type of contamination is common in [[food safety]], [[water supply]], and [[healthcare]] settings. For example, contamination on an [[agar plate]] can indicate the presence of unwanted microbial growth.

	~~There~~ are ~~several types of~~ contamination~~, including:~~		===Chemical Contamination===
			Chemical contamination occurs when harmful chemicals are present in the environment or in products. This can include [[pesticides]] in food, [[heavy metals]] in water, or [[toxic substances]] in the air. Chemical contamination can pose significant health risks to humans and the ecosystem.

	* '''[[~~Biological contamination~~]]~~''' - This occurs when living organisms~~, or ~~their products, enter a certain area~~. ~~This~~ can ~~include bacteria, viruses, fungi, parasites, and other microorganisms~~.		===Physical Contamination===
			Physical contamination involves the presence of foreign objects in a product or environment. This can include [[metal shavings]] in food, [[plastic fragments]] in water, or [[dust particles]] in cleanrooms. Physical contaminants can cause injury or compromise the quality of products.

	* '''[[Chemical contamination]]''' - This occurs when chemicals are introduced into an environment. This can ~~include pesticides~~, ~~heavy metals, and other toxic substances.~~		==Sources of Contamination==
			Contamination can originate from various sources, including:

	* ~~'''~~[[~~Radiological contamination~~]]~~''' - This occurs when radioactive materials are introduced into an environment.~~		* [[Industrial processes]]
			* [[Agricultural activities]]
			* [[Waste disposal]]
			* [[Natural disasters]]
			* [[Human activities]]

	== ~~Effects of Contamination~~ ==		==Prevention and Control==
			Preventing and controlling contamination involves implementing measures such as:

	~~The effects of contamination can vary greatly depending on the type of contaminant~~ and ~~the level of exposure. Some potential effects can include:~~		* [[Good Manufacturing Practices]] (GMP)
			* [[Hazard Analysis and Critical Control Points]] (HACCP)
			* [[Environmental monitoring]]
			* [[Personal protective equipment]] (PPE)
			* [[Regular cleaning and sanitation]]

	* '''[[Health effects]]''' - Contaminants can ~~cause a variety of~~ health ~~problems~~, ~~including respiratory issues, skin irritations, neurological damage~~, and ~~even cancer~~.		==Impact of Contamination==
			Contamination can have significant impacts on health, safety, and the environment. It can lead to:

	* ~~'''~~[[~~Environmental effects~~]]~~''' - Contaminants can harm wildlife, damage ecosystems, and pollute water sources.~~		* [[Foodborne illnesses]]
			* [[Waterborne diseases]]
	~~== Prevention and Control of Contamination ==~~		* [[Environmental degradation]]
