The examination of various elements in the milk products is very important in the food sector in respect of food quality and safety. The aim of this study was to determine the concentrations of calcium (Ca), cobalt (Co), cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), mercury (Hg), potassium (K), magnesium (Mg), sodium (Na), nickel (Ni), phosphorus (P), lead (Pb) and zinc (Zn) in white cottage cheese or cottage cheese supplemented with various additives (white, lacto-free, chive, tzatziki, mustard + onion, chili, active protein) available on the market of Slovakia. All essential elements were within the reference range. Cottage cheese enriched with tzatziki showed higher amount of Cu, Fe, K, and Zn. Mustard + onion cheese contained high values of Ca, Co, Mg, and Ni. In white cottage cheese high amount of Cr, Mn, and P was measured. The content of xenobiotic metals was below permitted limit. The contribution to PTWI (Provisional tolerable weekly intake) suggested very low dietary exposure to heavy metals as Cd, Hg, and Pb as well as other metals (Cu, Ni, and Zn) in cottage cheese. Numerous correlations between concentrations were observed. MOE (Margin of Exposure) evaluation denoted that average consumption of cottage cheese does not pose any high cardiovascular and nephrotoxicity threat.

Oral candidiasis may be white or red, classically presenting as cottage-cheese consistency plaques associated with symptoms of a burning mouth and dysgeusia. Standard first- and second-line antifungal medications can easily and safely be prescribed by dermatologists.

Article Synopsis
- The study focuses on analyzing lactic acid bacteria strains found in Ethiopian cottage cheese to understand their beneficial properties and potential risks, such as antibiotic resistance.
- Whole genome sequencing of three strains revealed that 54B and 54C are related yet distinct; neither strain contains harmful resistance or virulence factors and showcases valuable enzyme capabilities.
- The findings indicate that these strains could be safely used in food preservation and as means to prevent or treat infections, highlighting their probiotic potential.

Miniaturized procedures for chemical analysis give the possibility of a significant reduction in quantities of organic solvents used during isolation and determination processes. Liquid-liquid microextraction (LLME) using butanol as an extractant was investigated to selectively isolate oxytetracycline (OTC) antibiotic residues from dairy products. The optimal conditions of LLME were established after deproteinization of the samples.
