WORKING SURFACES HYGIENIC EVALUATION WITH ATP-BIOLUMINESCENCE - CATERING FACILITIES

Application of ATP-bioluminescence technique For monitoring of surface contamination in a catering facility has been investigated. Commercia l diagnostic reagents and bioluminometer have been used, giving result s in a very short time. Microbial contamination determined by plate co unt: has shown to be correlated, even if in a non-fully linear way, to instrumental measurements. Obtained data have given a general picture about hygiene conditions of the examined surfaces, to which the prese nce of microorganisms and tissular residuals have contributed.
