UV-C Radiation as a Factor Reducing Microbiological Contamination of Fish Meal

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. The research materials included salmon and cod meals. Samples of the fish meals...

Effectiveness of germicidal UV radiation for reducing fungal contamination within air-handling units.

Levels of fungi growing on insulation within air-handling units (AHUs) in an office building and levels of airborne fungi within AHUs were measured before the use of germicidal UV light and again after 4 months of operation. The fungal levels following UV operation were significantly lower than the levels in control AHUs.

Microbiological Contamination of Cosmetic Creams in Tehran

Abstract Background and Objective: Transmission of pathogens by cosmetics is one of the major health complications. Direct contact with contaminated non-standard cosmetics can have irreparable side effects for the consumers. Thus, the evaluation of microbial contamination in cosmetic products is important. The aim of this study was to assess the microbiological contamination of one of freque...
