Abstract:
In this study, arsenic content in 200 cat- and dog-food samples was estimated by means of electro thermal atomic absorption (Z-ETA-AAS), after using the wet digestion method, that were imported or commercialised in Italy from 2007 to 2012. The maximum value of total arsenic (As) in the samples was 12.5 mg kg-1. Some imported pet food was intercepted as a result of the Rapid Alert System for Food and Feed (RASFF) and rejected at the border or withdrawn from the Italian market, because they exceeded the maximum level of arsenic content imposed in Italy at the time of this study (2002/32/EC). All the samples with a signi cant arsenic level were sh-based. Recently, the 2013/1275/EC raised the maximum level of As permitted in sh-based pet food. However, the analysis of As species is required (EFSA 2014) in order to identify correctly the di erent contributions of dietary exposure to inorganic As and to assure pet food quality.
