List of participants 101 INTRODUCTION
COST Action 97 'Pathogenic micro-organisms in poultry and eggs' held its second
management committee meeting and workshop of 1996 in Rome, Italy.
The working group responsible for the organisation of the workshop was working group 2:
'Prevention of contamination of poultry meat, eggs and egg products'. After its first
workshop in 1995 (organised in cooperation with the XHth European Symposium on the
Quality of Poultry Meat and the Vlth European Symposium on the Quality of Eggs and
Eggs Products in Saragossa, Spain), the Istituto Superiore di Sanità, Rome, Italy, hosted
this second workshop. Participants from 18 European countries discussed their research
during the two-day meeting.
This third volume in the series of publications from COST Action 97 contains the papers
presented and it is expected that this publication will further contribute to knowledge
transfer throughout Europe.
We wish to use this opportunity to express our thanks and appreciation for the support
of this workshop to the European Commission, Directorate-General XII/BS.l
(Dr Ζ. Somogy), the Italian Poultry Federation, UNA (Mr R. Celadon) and the local
organisers at the Istituto Superiore di Sanità (Dr A. Macrì) and at the University of Bologna
(Prof. Dr A. Franchini).
