1. IntroductionWhile formaldehyde (FA) is naturally present as a low concentration metabolic intermediate in the cells of most living organisms [1,2], it is also found in several foods [1–3].However, the presence of FA in milk, whether for direct consumption or for processing, can be caused by the direct addition of this compound as an “unapproved” preservative to extend its shel ...

1. IntroductionAflatoxin M1 (AFM1) is the main metabolite of Aflatoxin B1 (AFB1), which is one of the four most common variants of Aflatoxins (AFs) [1–6]. There is sufficient evidence for the carcinogenicity of AFM1 alone or mixed with AFB1 and Aflatoxin G1 (AFG1) [7], although of lower potency than AFB1 [8,9]. When cattle ingest food or feed contaminated by AFs, it is estimated that up to 6 ...

1. IntroductionAflatoxin M1 (AFM1), it is one of five principal metabolites results from the hydroxylation process of Aflatoxin B1 (AFB1). Reaction of enzyme oxidase is associated to cytochrome P450 of the microsomes within the hepatocytes [1–6]. During this oxidative process, AFB1 is successively transformed into two intermediates, Aflatoxicol (AFL) and Aflatoxicol M1, before turning into A ...
