Abstract

Uvod: Prijevozna sredstva i vozači jedan su od najznačajnijih biosigurnosnih rizika od
prijenosa uzročnika bolesti unutar proizvodnih jedinica svinja. Prema propisima Europske unije
sva vozila za prijevoz svinja moraju biti očišćena i dezinficirana svaki puta nakon istovara, a
kad je potrebno i prije svakog utovara životinja, pomoću sredstava za dezinfekciju koje je
odobrilo nadležno tijelo. Cilj ovog završnog specijalističkog rada bio je utvrditi učinkovitost
sanitarnog pranja i dezinfekcije korištenjem dva komercijalno dostupna dezinficijensa na
prijevoznim sredstvima za svinje. Pretpostavka je bila da će ukupan broj bakterija nakon pranja
odnosno dezinfekcije biti umanjen za oko 90 %, a učinkovitiji dezinficijens preporučen je u
budućoj praksi tvrtke. Glavni cilj bio je izrada vlastitog standardnog operativnog protokola
postupaka čišćenja i dezinfekcije vozila za prijevoz svinja.
Materijali i metode: Kontrola provedbe sanitarnog pranja i dezinfekcije vozila za
prijevoz svinja provedena je tijekom studenog i prosinca 2022. godine uzimanjem brisova sa
sedam pozicija unutar četiri kamiona, nakon istovara svinja prije pranja, nakon pranja i nakon
dezinfekcije, u pet navrata. Dva kamiona dezinficirana su komercijalno dostupnim
dezinficijensom na bazi oksidacijskog sredstva, a dva dezinficijensom kojem je glavna aktivna
tvar glutaraldehid. Brisovi su analizirani u laboratoriju na ukupni broj bakterija i broj
enterobakterija. Rezultati su obrađeni statistički.
Rezultati i zaključak: Istraživanjem je potvrđena pretpostavka jer se pranjem i ukupni
broj bakterija i enterobakterija smanjio više od 90 % na svim pozicijama. Preostali ukupni broj
bakterija dezinfekcijom je značajno smanjen, u rasponu od 33 pa do 100 %, za oba korištena dezinficijensa. I broj enterobakterija značajno se smanjio na svim pozicijama nakon
dezinfekcije, a učinkovitijim sredstvom pokazao se dezinficijens na bazi oksidacijskog
sredstva, poglavito na pozicijama gdje se uobičajeno nalaze veće količine organske tvari. U
svrhu lakšeg obavljanja i kontrole provedbe postupaka pranja i dezinfekcije kamiona za
prijevoz svinja načinjen je prijedlog vlastitog standardnog operativnog protokola.

Abstract (english)

Introduction: Vehicles and drivers are one of the most significant biosecurity risks for
the transmission of disease agents within pig production units. According to European Union
regulations, all pig transport vehicles must be cleaned and disinfected each time after
unloading, and when necessary before each loading of animals, using disinfectants approved by
the competent authority. This specialist thesis aimed to determine the effectiveness of sanitary
washing and disinfection using two commercially available disinfectants on pig transport
vehicles. The assumption was that the total number of bacteria after washing and disinfection
would be reduced by about 90%, and more effective disinfectant will be recommended in the
company's future practice. The main goal was to create its own standard operational protocol
for the cleaning and disinfection of vehicles for the transport of pigs.
Material and methods: Implementation control of sanitary washing and disinfection of
vehicles for the transport of pigs was carried out during November and December 2022 by
taking swabs from seven positions inside the four trucks, after unloading the pigs before
washing, after washing and after disinfection, on five occasions. Two trucks were disinfected
with a commercially available disinfectant based on an oxidizing agent, and two with a
disinfectant whose main active ingredient is glutaraldehyde. The swabs were analyzed in the
laboratory for the total number of bacteria and the number of enterobacteria. The results were
processed statistically.
Results and conclusions: The research confirmed the assumption because washing
reduced the total number of bacteria and enterobacteria by more than 90% in all positions. The
remaining total number of bacteria was significantly reduced after disinfection, ranging from
33 to 100%, for both used disinfectants. The number of enterobacteria significantly decreased
in all positions after disinfection, and disinfectant based on an oxidizing agent proved to be
more effective, especially in positions where larger amounts of organic matter are usually
found. In order to make it easier to carry out and control the application of the procedures for
washing and disinfection of trucks for the transport of pigs, a proposal of our standard
operating protocol was made.
