to consult on the basis of the existing scientific literature and research on the
growth and survival of certain microorganisms.
If necessary, on the basis of the studies, the market foodstuff operators produce
additional studies that may include:
-
forecasting mathematical modeling for certain food products using the critical
factors of the growth and survival of these microorganisms in food;
-
research on ability properly seeded certain microorganisms to grow and
survive in food in terms of different expected storage conditions;
-
research on the growth and survival of certain microorganisms that may be
present in food during expire date in terms of prognosticated conditions of distribution,
storage and use.
The central referent laboratory for research of Listeria has developed guidelines
for the investigation of finished food products on their contents [7, 12, 13] for food
products, able to support the growth of Listeria monocytogenes. The quantity of
Listeria monocytogenes should not exceed 100 cfu/g by date of the expire.
Committee Regulation (EU) number 2073/2005 indicates the frequency of sample
selection of beef, pig, sheep, goat, horse carcasses and poultry with the help of facilities
that produce mince and meat semi-finished products. These food products are in danger
of being contaminated by microorganismus. Other food products have an average
degree of risk.

Carcasses, fresh meat, meat semi-finished products, ready-made products of
certain risk groups (infant formulae) belong to the category of high risk. The rest of the
products belong to the average degree of risk include. There is the possibility to reduce
sample selection in terms of satisfactory results over a long time (30 weeks or 15
months). Low degree of risk, which includes all other foodstuff, eliminates the
requirements of sample selection.
Laboratories that make researchers for food market operators, as well as research
methods establishment of microbiological criteria and matrix for the study were
accredited (standard of ISO 17025) [3,4,9, 11] by National Council for accreditation,
or, the equivalent organization, recognized by the European Agency for accreditation
or International Association of laboratory accreditation.
