Seroprevalence, Direct Detection and Risk Factors for Infection in Pigs in Serbia, and Influence of Biosecurity Measures.

Consumption of contaminated pork is a major risk factor for human infection. We thus conducted a cross-sectional survey on the seroprevalence of infection in a representative sample of slaughter pigs from throughout Serbia and examined the influence of farm biosecurity-related risk factors on infection. In addition, direct detection of the parasite (by mouse bioassay) or its DNA was performed in the hearts of a subset of seropositive sows.

Honey Bees and Their Products as Indicators of Environmental Element Deposition.

The aim of this study was to evaluate element (sodium, magnesium, potassium, calcium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, cadmium, and lead) deposition in honey bees (Apis mellifera L.) (worker bees, drone bees, and bee broods) and their products (wax and multifloral honey) in the central and north parts of Serbia using inductively coupled plasma mass spectrometry (ICP-MS). The study was carried out during the spring and summer seasons when the honeybees were active (2019).

The Toxic Element Concentration in Fish Tissues from Saničani Lake, an Urban Environment, in Bosnia and Herzegovina.

Concentrations of toxic elements (lead, cadmium, mercury, and arsenic) were measured in water, sediment, and four commercial fish species (Cyprinus carpio, Hypophthalmichthys molitrix, Silurus glanis, and Esox lucius) and their tissues (muscle, liver, and kidney) from Saničani Lake, Bosnia and Herzegovina. The concentration of toxic elements was measured by atomic absorption spectrometry. Toxic element concentrations were significantly affected by the fish species and tissues sampled.

Survival of Salmonella spp. in minced meat packaged under vacuum and modified atmosphere.

The effect of different modified atmosphere packaging regimes on the behavior of Salmonella spp. on minced meat was studied. Minced meat was experimentally contaminated with a Salmonella spp.
