1.5.1 Improvinginformation on foodborne diseases
As indicatedearlier, presentinformationis far fromcomplete and, in 50±60%of
casesof acuteenteritis,a causative agentis not detected (de Witet al., 2001)In
orderto definebetterthe burden of suchdiseases, noveltechniquesshould be
developedto test for unsuspectedpathogens. For this purpose,a multifactorial
approach is advocated and should include a study of the aetiology of
unsuspectedfoodborneagentsand theirepidemiology,the risk factors involved,
identificationof virulence genes, demographicfactors, clinicalcharacteristics,
etc. Knowledgeof the relevant risk factors and theircontributionto the problem
is particularly important for the development of appropriate intervention
strategies, and this aspect also needsto havean international dimension.
