Nitrate and nitrite, commonly added to meat products as sodium or potassium salts, serve multiple functions such developing characteristic flavor, inhibiting microbial growth, controlling rancidity by preventing lipid oxidation. Nitrites are recognized for their potential health risks humans. The present research aimed determine the amount of nitrite in four product categories Serbia over a period from 2015 2021. A total 923 samples were analyzed, including 293 finely chopped sausages, 203...

Porcine cytomegalovirus (PCMV) infection is widespread worldwide and has a high prevalence in swine herds, especially countries with intensive production. PCMV zoonotic can impact xenotransplants. It the third virus known to be zoonotic, following influenza (influenza A) hepatitis E genotype 3 (HEVgt3 or HEV-3). Wild boars, serving as reservoirs for various pathogens, including PCMV, pose risk both pig industry public health. This study aimed investigate Serbian wild boars using real-time...

Preventive biosecurity measures are essential control its spread, particularly broiler farms. This study aimed investigate the relationship between IB outbreaks and practices on a farm. Methods The farm, housing 96,000 broilers, experienced increased mortality (over 11%) during two consecutive cycles. Consequently, serological,...

Considering the sporadic number of scientific studies on vermicomposting apple pomace waste, this research conducts a comparative analysis processes using Eisenia fetida, focusing both independently and in combination with wheat straw and/or manure (experiment 1: 60% 40% cattle manure; experiment 2: 3: 80% pomace, 10% straw, 4: 100% pomace). After 240-day substrate transformation period, all four variations vermicompost produced demonstrated favorable sensory properties, along high...

One of the most important control parameters for mechanically separated meat (MSM) is calcium content, which indicates presence bone. The aim this study was to examine content in three types locally-produced MSM from differing animal species. Calcium quantified examined samples MSM, using indirect titration, and napthol indicators (eriochrome black T, hydroxy naphthol blue disodium salt) were used track end point titration. Each different showed a recovery more than 90% when examining...

Salmonella is a common contaminant of pork and can present health hazard to consumers. Therefore, for an effective control, the entire supply chain must be involved. The aim this paper examine survival Typhimurium in minced meat skin at different temperatures time. In meat, stored +4 ± 0.5°C during 72 h, number all three examined strains A, B, C decreased (p<0.01). +10 1°C after strain A was significantly higher (p<0.01), while B C, no statistically significant difference determined...

All tested (farm A, B C)...

The aim of this study was to determine the prevalence Salmonella along slaughter line and identify possible critical control points in one slaughterhouse facility located city Belgrade.In total, 700 samples were tested: two swabs from both sides carcass taken each 100 pigs. In way, 200 pig skin swab after stunning, processing chilling. Additional ileal contents also same pigs obtain a collection 270 isolates. All analyzed using standard culture methods serotyping. PFGE performed for 27...

The implementation of biosecurity measures as the first line defense is an essential prerequisite for preventing occurrence and spread infectious agents in flocks. Assessment on farms was carried out during farm visits based application appropriate questionnaire whereby farmer answered a number questions regarding implemented measures. study performed via Biocheck.UGent online survey 16 broiler region city Belgrade. capacity 25,000-100,000 broilers, placed 2-4 houses, depending farm. Farm...

Poultry represent an important global reservoir of Salmonella. salmonellosis results in great economic losses, and some serovars also have zoonotic potential. Some poultry can be infected with Salmonella without showing clinical signs the disease, but is, nevertheless, a significant source spread infection. Clinical symptoms range from digestive problems (white diarrhea, malabsorption) to bacteremia death. The aim this study was retrospectively show presence bacteria enterica subspecies...

As a preventive measure, biosecurity is the first line of defense against many pathogens.Applied measures can reduce prevalence Campylobacter infection in commercial broiler populations.A systematic evaluation, encompassing at least annual monitoring applied and on-farm highly recommended.This study was performed on three farms with aim to assess effectiveness applied.Broiler included previously had problems infections, therefore, after intervention through risk-based scoring system...

Food loss waste spoilage DamageThe world produces an enormous amount of food to sustain its population, yet a substantial portion it goes or is lost throughout the supply chain.Food refers reduction in quantity quality production, post-harvest, and processing stages, primarily developing countries with inadequate infrastructure storage facilities.It estimated that up one-third all produced globally before even reaches consumers.Food occurs mainly developed countries, at consumer retail...

Transport of animals from the farm to slaughterhouse carries numerous obstacles: manipulation and contact with man/operator, transport, different conditions environment which animal is now facing not used to, deprivation food water, changes in social structure, separation and/or mixing animals. As a consequence, can develop fear, dehydration, hunger, increased physical activity tension, fatigue injury. Inability overcome stress factors may further complicate highlight consequences have...

Listeria is the genus of a bacteria found in soil and water some animals, including poultry cattle. It can be present raw milk food made from milk. also live processing plants contaminate variety processed meats. Microscopically, species appear as small, Gram-positive rods, which are sometimes arranged short chains. In direct smears, they coccoid, so mistaken for streptococci. Longer cells resemble corynebacteria. Flagella produced at room temperature but not 37°C. Haemolytic activity on...
