Importers have been warned by the Standards Organisation of Nigeria (SON), about some cancer-causing substances found in some school uniform materials made by two China based companies.
In a statement released on Friday by Director General of SON, Osita Aboloma, disclosed that the azo dyes, which were found in some school uniforms from Hong Kong contained up to 173 milligrammess and 41 milligrammes per kilogramme of the tested samples respectively, which were well above the maximum allowed in the standard.
The names of the companies producing the materials, were given asSing Shun Fat School-Clothier Company and Zenith Uniform Company. According to him, use of the 4-amino azo dye has been banned in Europe, Japan and other parts of the world prior to the finding.
The SON chief executive advised importers of school uniform materials in Nigeria to endeavour to undergo the process of conformity assessment of such materials prior to import, through the SON’s offshore conformity assessment programme (SON-CAP) in order to avoid bringing them to the country. He added that SON will continue to work with other sister agencies like the Nigerian Customs Service and the nation’s Security apparatus, to protect Nigerians from the negative effect of substandard products. According to the statement, azo dyes could release carcinogenic substances known as aromatic amines when they mix with sweat, which accounted for the ban on the use of the dye in many countries of the world.
