Abstract
U prehrambenoj industriji, bakterija L. monocytogenes predstavlja veliki problem jer ima sposobnost preživljavanja u mnogim nepovoljnim uvjetima u kojima većina mikroorganizama nema mogućnost rasta i razvoja, kao što su vrlo niske temperature, tretiranje različitim sredstvima, promjena pH vrijednosti i slični postupci kojima se snižavaju optimalni uvjeti za razvoj mikroorganizama. Upravo zbog takvih karakteristika predstavlja problem preradi i skladištenju proizvoda u prehrambenoj industriji. Potrebno je redovito provoditi mjere opreza, čišćenje i dezinfekciju u pogonima za preradu hrane, posebice u pogonima za preradu svježeg voća i povrća, mlijeka i mesa jer je u takvim vrstama sirovina i prerađenih proizvoda zabilježena najveća prisutnost L.monocytogenes. S novim tehnologijama su se razvile i brojne metode kako za detekciju i izolaciju, tako i za kontrolu ove patogene bakterije. Ne primjene li se ispravni postupci obrade sirovina u proizvodnji, za uništenje L.monocytogenes, ona može izazvati ozbiljne zdravstvene probleme kod ljudi, odnosno može doći do pojave bolesti listerioze koju izaziva ova bakterija. Ona je posebno pogubna za rizične skupine ljudi poput trudnica, starijih osoba i osoba s oslabljenim imunitetom. Stoga je vrlo bitno znati koje su osobine ove bakterije, te sukladno s tim kako ju tretirati, odnosno kontrolirati njezin rast i spriječiti njezino širenje kako ne bi došlo prvenstveno, do opasnosti za zdravlje ljudi, ali i kvarenja hrane i velikih problema kontaminacije u pogonima prehrambene industrije.
Abstract (english)
In the food industry, L. monocytogenes is a big problem because it has the ability to survive in many adverse conditions in which the majority of microorganisms has no possibility of growth and development, such as very low temperatures, the treatment with different compounds, a change in pH and similar procedures which reduce the optimal conditions for microbial growth. Because of these characteristics it is a problem with processing and storage of products in the food industry. Precautions, cleaning and disinfection of food processing units should be carried out regulary, particularly in the processing units, fresh fruits and vegetables, milk and meat, because in those raw materials and processed products the largest presence L.monocytogenes has been recorded. With new technologies more methods have been developed for the detection and isolation, and for control of these pathogenic bacteria. If procedures of processing raw materials in the production are not carried out correctly, to destroy L.monocytogenes, it can cause serious health problems in humans and can cause illness listeriosis caused by this bacterium. It is particularly devastating to the sensitive groups of people such as pregnant women, the elderly and people with supressed immune systems. It is, therefore, very important to know which features are of these bacteria, and according to that how to treat or control its growth and prevent its spread to avoid primarily the risk to human health, as well food spoilage and contamination in food industries.
