Salmonellosis and campylobacteriosis are among the most frequently reported foodborne diseases worldwide. In order to ensure that it is underpinned with the most robust scientific data, the 40th Session of CCFH requested FAO and WHO to provide them with the necessary scientific advice. In response to that request, FAO and WHO convened an ad hoc Technical Meeting from 4 to 8 May 2009, in Rome, Italy.
