Industrial workers are exposed to different types of risks, including occupational exposure to biological agents such as viruses, bacteria, fungi, parasites, spores or toxins capable of causing some type of infection, disease or toxicity. A great variety of these pathogens have been identified on different surfaces within work facilities, persisting in some cases after the usual cleaning days, and even surviving for long periods of time. Preliminary findings indicate that hygiene processes in two industries allowed a statistically significant decrease in the presence of E. Coli and Sars-Cov-2, on surfaces within the facilities. On the contrary, in a third industry it was observed that hygiene and cleaning processes failed to effectively reduce the presence of pathogens Hygiene audit in textile industry facilities should include the ability to find and identify biological hazards that are still present on surfaces, once the routine cleaning and disinfection protocols established by the organization have been executed. For this work, we propose the complementary practice of three procedures: microbiological determination, using swabs or contact plates, visual determination with ultraviolet light, to verify the degree of cleaning efficiency, and specific determination, consisting of RNA detection. of SARS-CoV-2 virus (causing COVID-19) in environmental samples of surfaces by the real-time PCR method.
