Effect of Radiant Catalytic Ionization and Ozonation on spp. on Eggshells.

Three strains were used in the study (serovars: , and ). This study evaluated the efficacy of radiant catalytic ionization (RCI) and ozonation against spp. on eggshell (expressed as log CFU/egg).

Prevalence and antimicrobial susceptibility of Listeria monocytogenes strains isolated from a meat processing plant.

Introduction And Objective: The ability of to create biofilm results in the higher resistance to disinfectants and determines the need to search for effective methods of eradication. The aim of the study was to assess the level of contamination in the environment of a meat processing plant. The sensitivity of tested isolates to various antimicrobials used for disinfection purposes was also estimated.

Assessment of the Prevalence and Drug Susceptibility of Strains Isolated from Various Types of Meat.

are the etiological factor of listeriosis, and their main source for humans is food. The aim of the current study was to assess the contamination of various types of meat and the drug susceptibility of isolated . Between 2016-2018, 6000 swabs were taken (2000 annually) from the surface of pork, beef, and poultry.

Disinfectant Susceptibility of Biofilm Formed by under Selected Environmental Conditions.

is a one of the most important food-borne pathogens. Its ability to form biofilm contributes to increased resistance to disinfectants and inefficient disinfection, posing a serious threat for the food industry, and in the end the consumer. The aim of this study was the comparison of the biofilm formation ability of strains on stainless steel, under different environmental conditions (temperature, pH, NaCl concentration, nutrients availability), and the assessment of biofilm susceptibility to disinfectants.

UV-C radiation as a factor reducing microbiological contamination of fish meal.

Fish meals, added to feeds as a source of protein, may contain pathogenic bacteria. Therefore, effective methods for their sanitizing, such as UV-C radiation, are needed to minimize the epidemiological risk. The objective of this study was to evaluate the effect of UV-C radiation on the sanitary state of fish meals.

Use of the Filter-Sandwich carriers in continuous effectiveness monitoring of slurry treatment methods as an element improving biosafety in agriculture.

Slurry, due to high microbiological contamination, requires hygienization before spreading. The agricultural usage of treated slurry has to guarantee biosafety. Therefore, constant monitoring of the slurry treatment process should be conducted.

Sanitization efficacy of anaerobic digestion and aeration of slurry from the aspect of limiting emission of Salmonella into the environment.

The aim of this study was to estimate the usefulness of mesophilic anaerobic digestion and aeration for sanitization of slurry from the aspect of limiting transmission of Salmonella into the environment. Material for the study was fresh pig slurry. Collected samples were subjected to anaerobic digestion at 35°C and aeration with an initial temperature of 35°C.
