• ‘The procedure whereby health measures are taken to control or kill the insect vectors of human diseases present in baggage, cargo, containers, conveyances, goods and postal parcels (WHO, 2005).
• ‘The process of destroying or inactivating pathogenic organisms (bacteria, viruses, fungi and protozoa) by either chemical or physical means (Symons et al., 2000).’

It defines disinfection by-product as: ‘The formation of chemical by-products (inorganic or organic) that results from the use of chemical disinfectants in water treatment (WHO, 2008).'
