Abstract

During the carrying out of the monitoring plan as part of the Regional Law n. 3/2005 emerged, in 2008, the well known “buffalo milk crisis” that led to the enactment of other monitoring plans targeted to the research of dioxins in food. From the last monitoring plan on PCDD/Fs and DL-PCBs in Campania Region, named as “Surveillance plan 2011-2014”, all dairy products from N. 50 farms intended to the production of bovine, buffalo and ovine milk, resulted compliant to the maximum levels fixed by EU in Regulation 1259/2011, suggesting the effectiveness of the restrictive measures on farming practices applied after the sanitary emergency of 2008. On the other hand, the action limits reported in EU Recommendations 516/2011 and 711/2013 were exceeded in two sheep farms and two buffalo farms, to represent the critical issues that nowadays exist.

Highlights

The PCDD/Fs are a group of 75 polychlorinated dibenzo-p-dioxins and 135 polychlorinated dibenzofurans, belonging to the group of human endocrine disruptor
Samples were collected by veterinary authorities according to ex EC Reg. 252/2012, avoiding any possible source of contamination by dioxins and PCBs; 5 aliquots of 1 kg each per sample were sent to the laboratories of Istituto Zooprofilattico Sperimentale del Lazio e della Toscana (IZSLT) and Istituto Zooprofilattico Sperimentale del Mezzogiorno (IZSM), recommended by the European Commission, working in conformity with ex Reg
Analysis was performed on Thermo Fisher Scientific MAT 95 HRGC/HRMS, during the first period of monitoring plan (IZSLT), and, further, Thermo Fisher Scientific DFS HRGC/HRMS (IZSM) both at a mass resolution of R at minimum of 10,000 by isotope dilution with every analysed compound having its own 13C12-labelled internal quantification standard added to the sample before extraction, according to US-EPA method 1613b [4]

Summary

Introduction

The PCDD/Fs are a group of 75 polychlorinated dibenzo-p-dioxins and 135 polychlorinated dibenzofurans, belonging to the group of human endocrine disruptor. PCDD/Fs are unwanted by-products of several processes, whereas PCBs were intentionally produced; both are chemically inert and resistant to biodegradation; they are extremely persistent in the environment They are lipophilic compounds they accumulate in fat tissues and along the food chain. (2015) Monitoring Plan on PCDD/Fs and DL-PCBs Milk Contamination in Campania Region (Italy). 3/2005 (aimed to the screening of several environmental pollutants in food, including dioxins) and led to the enactment of an EU-Ministry of health extraordinary plan in the period 2008-2009 that was targeted to the research of dioxins in food From this plan, several farms resulted contaminated, the application of suitable restrictive measures led the farmers to decontaminate the animals. The monitoring plan on PCDD/Fs and DL-PCBs contamination in Campania Region of 2011, whose data are presented in this work, fits into this context of sanitary emergencies. Water was purified using a Milli-Q system (Merck Millipore Corporation, Darmstadt, Germany)
