Microbiological food safety generally does not require an
assessment of benefits as the consequences of microbial contaminants
are usually only adverse; depending mainly on different
types of hazards and foods as well as the susceptibility of individual
consumers and consumer groups to infection or intoxication
(Buchanan et al., 2000). However, interventions leading to the
reduction of microbiological risk can be regarded as a positive effect
and a public health benefit.
