A survey on 73 milk samples from different animal breeds and 24 dairy products samples from Sicily, Italy, was carried out for the presence of aflatoxin M1 (AFM1) by LC-fluorescence detection after immunoaffinity cleanup. AFM1 was detected in 48% and 42% of the milk and dairy samples at concentration ranges between <5.0-16.0 and <5.0-18.0 ng L-1, respectively. Within the raw milk samples, 92% had an AFM1 content below 5.0 ng L-1, in 7% of the cases it was in the range 5.0-10.0 ng L-1 and 1% was contaminated between 10.0 and 20.0 ng L-1. For the dairy products, ultra-high-temperature treated (UHT) milk, milk cream and cheese, the incidence was 42%, of which 83% contained less than 5.0 ng L-1 and 17% contained 10.0-20.0 ng L-1 AFM1. The levels of contamination found justify continuous monitoring for public health and to reduce consumer exposure.

Abstract
A survey on 73 milk samples from different animal breeds and 24 dairy products samples from Sicily, Italy, was carried out for the presence of aflatoxin M1 (AFM1) by LC-fluorescence detection after immunoaffinity cleanup. AFM1 was detected in 48% and 42% of the milk and dairy samples at concentration ranges between <5.0-16.0 and <5.0-18.0 ng L-1, respectively. Within the raw milk samples, 92% had an AFM1 content below 5.0 ng L-1, in 7% of the cases it was in the range 5.0-10.0 ng L-1 and 1% was contaminated between 10.0 and 20.0 ng L-1. For the dairy products, ultra-high-temperature treated (UHT) milk, milk cream and cheese, the incidence was 42%, of which 83% contained less than 5.0 ng L-1 and 17% contained 10.0-20.0 ng L-1 AFM1. The levels of contamination found justify continuous monitoring for public health and to reduce consumer exposure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
