Effectiveness of sanitation regime in a milking parlour to control microbial contamination of teats and surfaces teat cups'.

Introduction And Objective: The major sources of bacterial contamination of raw milk are post-harvest manipulation; therefore the disinfection of teat and teat cups which decrease the bacterial load has a positive impact on minimizing new infection rates. The aim of the study was determination of the incidence of pathogens on investigated surfaces, evaluation of the effectiveness of sanitation regime in the reduction of surface microbial load, and determination of the effectiveness of mechanical cleaning of teats in a milking parlour for dairy cows.

Material And Methods: Samples from surfaces were taken by microbiological swabs using a sterile cotton swab from area of 5×2 cm.

Risk of exposure to acrylamide.

Objectives: Acrylamide is a toxic compound that can be found it both occupational and non-occupational environments. This study focuses on its sources and health effects of its exposure.

Methods: Adverse effects of acrylamide, especially carcinogenic, genotoxic, and teratogenic were reported in many studies conducted on animals.

Concentrations of selected toxic elements in ewe living near an environmentally loaded area of eastern part of Slovakia.

Introduction And Objective: Research focused on the monitoring of selected heavy metals in ewes' blood. Concentrations of selected toxic elements, lead, cadmium and zinc, in ewes living near an environmentally-loaded area, concerned 15 ewes (aged 3-4 years) in good physical condition, during the spring of 2014 and 2015 in the eastern part of Slovakia. The aim of the research was to determine the concentration of selected heavy metals and state the correlations of selected heavy metals in ewes' blood.
