This document specifies a method for the determination of aflatoxin M1<\/sub> content in milk and milk powder. The lowest level of validation is 0,08 \u00b5g\/kg for whole milk powder, i.e. 0,008 \u00b5g\/l for reconstituted liquid milk. The limit of detection (LOD) is 0,05 ?g\/kg for milk powder and 0,005 ?g\/kg for liquid milk. The limit of quantification (LOQ) is 0,1 ?g\/kg for milk powder and 0,01 ?g\/kg for liquid milk.<\/p>\n The method is also applicable to low-fat milk, skimmed milk, low-fat milk powder and skimmed milk powder.<\/p>\n Milk and milk powder.
