عنوان انگلیسی THE MICROBIOLOGICAL MONITORING OF RECYCLED PAPER TISSUES
چکیده انگلیسی مقاله In order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in Iran, random samples were taken for one year with the cooperation of the Iranian Standard and Industrial Research Institute (Karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable contamination with microbiological elements (bacterial & fungal) were assessed using proper ordinary and specific culture environments while also performing confirmation tests. Considering all aspects of this study including easy identification, high precision, simplicity of application, economic justification and observation of better results, the method which applies ringer 1/4 solution as the thinner environment was preferable to the saline peptone water solution. No contamination with Staphylococcus aureus, Streptococcus faecalis, Pseudomonas aeroginosa and E.coli bacteria was observed, but the excessive contamination with the mesophillic bacteria was confirmed. Among the 27 samples tested with the ringer 1/4 method, 8 cases (29.6%) were excessively contaminated with the mesophillic bacteria and one case (3.7%) with fungi. Meanwhile, out of the 43 samples that were tested with the saline peptone water solution, there was no excessive contamination with mesophillic bacteria and only one case (2.3%) of fungal contamination was observed.
