3 Since 2009 the lighthouse at he entrance of the harbour, the Tower of Hercules is inscribed ib on UNESCO s World Heritage List It was built by Romans in late 1 st century A.D and was restored in the 18 th century which is unique as it is the only lighthouse of Greco-Roman antiquity to have retained a measure of structural integrity and functional continuity.

Services work for scientist from our and other universities, public organisations and private customers. Instruments for GC, HPLC, GC/MS, LC/MS and sample preparation 2 Thermo Polaris Q ion traps 1 AB API Q 1 Thermo Orbitrap Discovery mass spectrometer 1 Thermo MAT 95 XP magnetic sector mass spectrometer coupled to two Trace GC analysis of PCDDs/Fs and dl-pcbs Since May 2009 we are accredited as test laboratory according to ISO/UNE/EN for the determination of PCDDs/Fs in food and feed. We are the 4th laboratory in Spain achieving this accreditation. 4

6 The Galician sector in Spain Total production 2,700,000 tons % Spain 5 th producer of Spain gmp.galis borns to give an answer to Pressure of administration that is applying more strictly controls due too new legislations. Pressure of livestock sector to increase levels on food safety. Pressure of public opinion that is increasingly sensitized by the recent crises. Pressure of surrounding countries with high controls, that increase the risk of arrival of raw materials with poorer quality. 6

14 PCDDs/Fs and dl-pcbs: results RASFF notification Notification is only for PCDDs/Fs because Local Government subtracted uncertainty to all results According with this criterion: 1. Sample H.F. 3 was the only one that exceeded the legal limit for WHO-TEQ PCDDs/Fs 2. TOTAL WHO-TEQ was always under legal limit 14

15 PCDDs/Fs and dl-pcbs: results No analysis of the original palm oil Analysis of a palm soap produced with the same oil Analysis of 2 feeds containing the hydrogenated fat 1.40 Both feeds had very low levels of WHO-TEQ Total WHO-TE EQ (pg/g) WHO-TEQ PCB WHO-TEQ PCDD/F Palm soap levels l were low and lower than directive limit Palm oil was not contaminated PCDDs/Fs can be formed during hydrogenation 0.00 H.F.
