Raw milk samples from fourteen districts of the Punjab province, Pakistan, were analyzed for the contamination of aflatoxin M-1. The analysis was carried out by using immunoaffinity columns and Fluorometer. All of the samples analyzed were found contaminated with aflatoxin M, (AFM(1)). However, the level of aflatoxin M I in 96.4% samples was below the US tolerance limit of 0.5 mu g/L. Only 3% samples showed AFM(1) concentration higher than the US maximum limit. The 99.4% samples exceeded the European Union limit, i.e. 0.05 mu g/L. Seasonal effect was also studied on the presence of AFM(1) concentration in milk. The data were analyzed statistically by applying ANOVA. The results urge the need to impose a maximum permissible limit for AFM(1) levels in milk and milk products in Pakistan. This study, which is the first one of its nature on aflatoxin M, in Pakistan, suggests a regular monitoring of AFM(1) in milk and milk products in the country. (c) 2007 Elsevier Ltd.
