Abstract

AbstractMilk products with aflatoxin M1 (AFM1) contamination are a lethal dilemma worldwide due to their carcinogenic and mutagenic effects especially in developing countries. This study investigated the occurrence of AFM1 in milk-based mithae samples marketed in Lahore, Pakistan. Two hundred (n = 200) different types of mithae samples were analyzed for AFM1 using a HPLC florescence detector. Results showed that AFM1 was present in 76% of the analyzed samples, of which more than 80% had a much higher level of AFM1 than the European Union permissible level of i.e.0.05 μg/kg in milk products. The aflatoxin M1 in all the tested samples was observed in the range of 0.004 to 1.49 μg/kg. On average, the Gulab Jamun and Malai Laddu showed the highest level of aflatoxin M1 i.e. 1.49 and 1.17μg/kg, respectively. The lowest amount of aflatoxin M1 was found in Kalakand samples 0.004μg/ kg. The conclusion drawn from this data revealed that almost three-fourths of the mithae samples were highly contaminated with AFM1 due to their main component, milk. The consumption of milk-based mithae is popular due to health benefits as well as being part of tradition. Instead of being nourishing and beneficial, it is been found to be hazardous to human health due to aflatoxin contamination. Continued monitoring of aflatoxin M1with strict rules and regulations is required to prevent aflatoxin accumulation in this favorite food commodity.

Highlights

  • Milk products with aflatoxin M1 (AFM1) contamination are a lethal dilemma worldwide due to their carcinogenic and mutagenic effects especially in developing countries

  • 2.1.2 Chemicals and Reagents: The standard for aflatoxin M1 in acetonitrile was purchased from Sigma Aldrich (Germany), whereas the immunoaffinity columns (IAC) Afla M1TM were purchased from VICAM (Watertown, MA, USA)

  • Milk is a highly nutritious constituent of mithae it tends to have a maximum quantity of aflatoxin M1, a serious risk to consumer health and food safety [19,29]
