2. An FSO set at the point of consumption relates to the
level of the pathogen that can be consumed without
an unacceptable impact on public health at the population
level; it relates to the actual exposure and
the response at population level; on a population
level, exposure is composed of several, quite variable
factors, most importantly the concentration and frequency
of the hazard occurring in the product at
the moment of ingestion and the amount of product
ingested. Also, the ALOP relates to exposure and
response at population level, thus to consumption
patterns affecting actual ingestion next to the level
and frequency of the hazard occurring in food. However,
while ALOP relates to this on a higher level and
encompasses all factors, an FSO needs to be meaningful
to the supply chain and effective in delivering
the intention of risk management in terms of food
safety. For this reason, an FSO can refer to either a
concentration or a frequency or to both
