  • Title: [Medical waste. 1. Microbiologic studies of wastes of various specialties at a large and small hospital in comparison to housekeeping waste].
    Author: Jager E, Xander L, Rüden H.
    Journal: Zentralbl Hyg Umweltmed; 1989 Jun; 188(3-4):343-64. PubMed ID: 2757749.
    Abstract:
    Hospital wastes, similar to household refuse, from normal and high risk areas of a big and a smaller hospital were tested quantitatively and qualitatively for nosocomial infective agents. The results were compared with those of household refuse. 20-25 samples from care and operating wards were examined each for 3 months. The whole content of a waste bag was suspended without a preceding sorting. After this treatment the eluat was microbiologically examined. The results of the test proved that the germ concentration of the hospital waste was less or similar than that of household refuse. The median for gram negative rods in household refuse was e.g. 4 log10-steps higher than in wastes from operating wards. The statistical analysis confirmed these highly significant differences between the wastes from the high risk operating areas of the big and smaller hospital and the household refuse for all investigated bacteria groups. There are nearly no differences between the wastes from normal wards and from household refuse regarding germ concentration for different groups, e.g. gram negative rods or D-streptococci, and no higher germ concentration in any case. In conclusion hospital wastes must be disposed with special hygienic measures inside the hospital, outside the hospital they can be disposed together with household refuse.
