Aflatoxin B_1 contamination in feed from Puglia and Basilicata regions (Italy): 5 years monitoring data

摘要

During a 5-year period from 2010 to 2014, n = 919 samples of feed and ra_w materials were analyzed for anatoxin B] (AFBO contamination using accredited ELISA screening methods. Only 0.76 % of these samples were non-compliant with maximum levels set bythe European Union Regulation 32/2002. Non-compliant samples were mainly from the province of Bari (n= 3 samples, mean AFB_1 value 7.03 mug/kg), although the highest AFBX levels were found in two samples from the provinces of Foggia and Brindisi, at 32.6 ± 3.6 mug/kg and 31.0 ± 4.0 mug/kg, respectively. Mean AFBt levels in samples contaminated but compliant with the limits ranged from 1.4 to 2.2 mug/ kg. Considering the great importance of climate conditions in mycotoxins production, during crops production and during the critical phases of materials storage and/or transport, to better understand the variability in contamination levels, the analytical results were reviewed in term of temperature and relative environmental humidity in the sampling areas. Correlations between aflatoxin B_1 levels in feed and these climate factors might explain seasonal and annual variations in contamination levels. The data from the present study provide useful suggestions for the organization of targeted monitoringplans and the protection of consumers, as well as for improvement in the quality standards of zootechnological activities and feed industry.
