Formaldehyde Adulteration in fish, food, meat, milk, water
Description
Formaldehyde is the simplest aldehyde. It is widely employed in industry (meat, fruits, fish, water) for wide range of applications, as a disinfectant and is a commonly utilized tissue fixative and embalming agent. Formaldehyde is naturally present in all tissues and body fluids. Recently, it has been shown that some cancer types exhibit elevated formaldehyde levels. Examples of foods known to contain naturally occuring formaldehyde.
