“…Cleaning is routinely monitored by visual audits. While looking to see if a ward is 'clean' may aesthetically satisfy, it does not provide a reliable assessment of the infection risk for an individual patient in that ward (11) . The organisms that cause infection are invisible to the naked eye and their existence is not necessarily associated with any visible signs (10) .…”

Surface cleaning is a well-known control procedure against the dissemination of microorganisms in the hospital environment. This prospective study, carried out in an intensive care unit over the course of 14 days, describes the cleaning/disinfection conditions of four surfaces near patients. In total, 100 assessments of the surfaces were carried out after they were cleaned. Three methods were used to evaluate cleanliness: a visual inspection, an adenosine triphosphate (ATP) bioluminescence assay and testing for the presence of A inspeção visual não se mostrou medida confiável para avaliar a limpeza das superfícies.Os resultados demonstram que a rotina de limpeza adotada precisa ser revista. no se mostró una medida confiable para evaluar la limpieza de las superficies. Los resultados demostraron que la actual rutina de limpieza precisa ser modificada.

Adenosine-5'-triphosphate (ATP) is a high-energy molecule playing a role of universal energy carrier used in cell metabolism. Since ATP is present in both prokaryotic and eukaryotic cells, this coenzyme can be used to determine a hygiene state. During last decade there has been a significant growth of practical applications of ATP measurements. ATP tests are commonly used for an assessment of hygienic conditions in food industry, residential buildings and hotels. In comparison with traditional and time-consuming laborious microbial analysis the measurement of ATP provides a quick indicative on-site data, characterizing microbial and organic contamination to support decision-making with regards to adequate corrective and preventive actions. This paper demonstrates applications of ATP in practice and, particularly, in water treatment technology and wastewater processing. The review highlights opportunities for using the test for the optimization of water treatment facilities and pipe networks functioning in order to assess wastewater toxicity and wastewater treatment process efficiency. Other areas of application are also addressed. The review of literature indicates that ATP used in different areas of industry can be considered as a diagnostic method -complement the classical methods -useful for identification of hygiene risks as well as a tool for a real-time management of health and environmental risks.

“…The reaction also requires oxygen and releases light in proportion to the concentration of microbial ATP in the sample. The intensity of the light is measured by a photosensing piece of equipment, called a luminometer (Baker et al, 1992;Griffith et al, 2000;Costa et al, 2006). These luminometers detect the presence of microbial contamination in milk products by detecting the presence of microbial ATP.…”

New approaches are needed to quickly indicate possible contamination of UHT milk, among them the technique of ATP-Bioluminescence. Therefore, the aim of this study was to compare the results of culture methods with the results of ATP-Bioluminescence technique of 102 UHT whole milk samples incubated at 48, 72, and 168 hours. UHT milk samples were analyzed for the presence of mesophilic and psychrotrophic aerobic microorganisms using Plate Count Agar (PCA), Brain-Heart Infusion (BHI) media and Petrifilm TM Aerobic Count (AC) plates. The ATP-Bioluminescence technique was applied through the Microbial Luminescent Screening (MLS) system. Significant correlations were found between counts of aerobic mesophilic microorganisms on PCA, Petrifilm TM AC, BHI and results of ATP bioluminescence technique (P≤0.05). The ATP-Bioluminescence technique had higher correlation with counting method in PCA than BHI media. At lower pass/fail limits of Relative Light Units (60, 50, 45 and 40 RLU), the number of samples identified as positive increased and statistically agreed with aerobic mesophilic microorganism counts (P>0.05). For the dairy industry, the ATP-Bioluminescence technique may become an important tool that assists the official methods to quickly monitor the microbiological quality of UHT milk though this will likely require a threshold below 150 RLU.Keywords: ATP-Bioluminescence, microbiology, milk, quality, UHT RESUMO Novos métodos são necessários para detectar de forma rápida a contaminação do leite UAT, entre eles, a técnica de ATP-Bioluminescência. Portanto, objetivou-se comparar os resultados de métodos de cultura tradicionais com os resultados de ATP-Bioluminescência de 102 amostras de leite UAT integral incubadas por 48, 72 e 168 horas. Os leites UAT foram analisados quanto à presença de microorganismos aeróbicos mesófilos e psicrotróficos usando os ágares PCA, BHI e placas Petrifilm TM AC. A técnica de ATP-Bioluminescência foi aplicada por meio do sistema Microbial Luminescent Screening (MLS). Significantes correlações foram obtidas entre as contagens de micro-organismos mesófilos
