The best action to reduce the risks of contamination by pathogenic microorganisms is the use of prevention measures, mainly the hygiene and decontamination of environments, food, objects, among others. Generally, chemical germicides are used to promote such actions, however, this method may not be as efficient. Therefore, new technologies are necessary, one of which is the use of radiation in the shortwave ultraviolet spectrum (UV-C), a method that has been recognized as very effective for decontaminating various surfaces. Therefore, the objective of this work was to record recent applications for microbiological disinfection and sterilization using UV-C electromagnetic radiation, through an Integrative Literature Review. The platforms used to survey the works were: Google Scholar, Web of Science and Virtual Health Library (VHL). The following question was chosen to guide the research: “What are the recent and effective applications of UV-C radiation in the disinfection and sterilization of microorganisms in different areas, and their main advances and challenges?”. After the survey, 525 works were analyzed, of which 100 were selected to be read in full, and, at the end of the analysis, 30 works were included and presented in this review. The results were organized in a synoptic table that presents the synthesis of the selected studies. All the works analyzed presented promising results regarding the inactivation of microorganisms in different contexts using shortwave ultraviolet radiation (UV-C). This review provides a solid basis for implementing UV-C-based disinfection and sterilization practices in a wide variety of scenarios, contributing significantly to preventing the spread of infectious diseases and promoting health security and public health.

The present work aims to characterize the routine and activities carried out during the period referring to the Mandatory Supervised Internship (ESO), which took place between June 19, 2023 and August 31 of the same year. The internship was carried out under the supervision of veterinarian Kattarina Keylla Monteiro Borges de Oliveira and under the guidance and supervision of Prof. Dr. Elizabeth Sampaio de Medeiros, at the Meat and Milk Inspection Laboratory of the Federal Rural University of Pernambuco (LICAL/UFRPE) and at the Masterboi LTDA distribution center, both located in the city of Recife - PE. At LICAL, the laboratory routine was monitored, organization and verification of available culture media, preparation of materials used in research, in addition to microbiological analysis carried out on site. Among the activities carried out, there was monitoring of the daily activities of the industry, from the reception and analysis of raw materials, collection of samples for microbiological tests, monitoring of the manufacturing process of by-products and guaranteeing food quality, support in self-control procedures, inspection of meat products and storage chambers. The characteristics relating to the locations where the ESO took place are reported in this document, as well as a description of the activities carried out during the internship period. Subsequently, there is a study on the evaluation of the effectiveness of hydrogen peroxide as a sanitization measure in industry. The internship period made it possible to align theoretical knowledge with practical knowledge, through practical experience, thus getting to know the routine in the area of Food Inspection of Animal Origin and Industrial Quality Assurance.
