Transmission pathways of foodborne viruses include contamination of food by infected food handlers, by contamination of food during the production process and by consumption of products of animal origin harbouring a zoonotic virus. Viral foodborne illnesses, which have become a significant cause of all reported foodborne illnesses in recent years and considered as an emerging risk in veterinary public health. Microbiological genomics studies discovered that Noroviruses and hepatitis A viruses were primarily associated with food-handler transmission and sewage-contaminated foods. In contrast, hepatitis E was associated with consumption of raw or undercooked meat of pig or wild animals. In order to facilitate source attribution and identify risk prevention measures, Routine harmonized surveillance of viral outbreaks, and surveillance of virus occurrence in food commodities, in combination with systematic strain typing, and joint expertise from veterinary, food, and clinical microbiologists would be recommended.

Sremski kulen is a dry fermented sausage which is traditionally manufactured in Northwestern Serbia, a region known as Srem. As a part of the gastronomic heritage, Sremski kulen has been produced for centuries in Srem village households according to traditional recipes and technology. A nutritionally valuable meat product, Sremski kulen is widely appreciated in the country. Due to its authentic production and recognizable characteristics, Sremski kulen has been protected with a designation of origin according to the Serbian legislation (Law on Geographical Indications No. 18/2010, 2010). Nowadays, Sremski kulen is manufactured in small household enterprises according to the protected recipe, without starter cultures or additives. Sremski kulen is produced from high-quality pork with the addition of salt and red spicy paprika, stuffed into pork cecum, and preserved by smoking, fermentation, and drying (Vuković et al., 2011). Ripened products are characterized by specific peppery taste, pleasant and aromatic odor, dark red color, as well as firm consistency (Suvajdžić et al., 2018).

2018): Assessment of some parameters productivity and quality of populations Phleum pratense L. grown in conditions of Serbia.-Genetika, Vol. 50, No. 1, 1-10.Phleum pratense (L.) is the important forage grass species in Serbia. The study was conducted on 20 autochthonous population of Phleum pratense (L.), originating from Western Serbia. Plant height, protein content and crude cellulose content had a high direct impact on yield. Populations of PP16, PP20, PP2 and PP9 had the significantly higher yield of the raw matter compared to all the tested population and the highest values for the other evaluated parameters, also. The average yield of crude biomass was positive statistically highly significantly correlated with plant height (r=0.87**), and positively significantly correlated with a content of crude proteins and positive non significant correlated with crude cellulose (r=0.42 ns ). Based on obtained values and by the appropriate choice of selection methods, we conclude that we have excellent genotypes, PP16, PP20, PP2 and PP9 for a successful selection process in order to obtain new high yielding varieties of Phleum pratense.

Izvod Vremenski i klimatski uslovi koji su bili atipični za umereno kontinentalno proleće i leto 2012. godine smatraju se jednim od razloga kontaminacije useva mikotoksinima u Srbiji. Upotreba hrane za životinje poreklom iz žetve 2012. god. za posledicu je imala pojavu aflatoksina M 1 (AFM 1) u mleku krava. Kvantitativni ELISA testovi korišćeni su za analizu uzoraka hraniva, odnosno mleka. Konfirmacija pozitivnih rezultata dobijenh imunoenzimskim testom obavljena je pomoću UPLC-MS/MS metoda. Od 281 uzorka potpunih smeša za ishranu krava muzara, 67 uzoraka (24%) je sadržalo aflatoksin B 1 (AFB 1) u koncentraciji većoj od vrednosti MDK (maksimalno dozvoljena količina) od 0,005 mg/kg [4]. Uzorci kukuruza su, takođe, ispitani na prisustvo AFB 1 i utvrđena je kontaminacija 22% uzoraka iznad vrednosti maksimalno dozvoljene količine (0,03 mg/kg). Uzorci druge vrste hraniva, kao što su suncokretova sačma, seno, kukuruzna silaža i repini rezanci bili su negativni na prisustvo aflatoksina B 1. Sadržaj AFM 1 u 934 "skrining" pozitivna uzorka je bio u opsegu 0,005-1,25 µg/kg. Najviši stepen kontaminacije zabeležen je tokom marta 2013, kada je 65% ispitanih uzoraka mleka sadržalo više od 0,05 µg/kg, a 13% više od 0,5 µg/kg aflatoksina M 1 .
