background; providing safe drinking water is a prime concerninany community. this analytical study was carried out to evaluate the microbial quality of drinking water in rural areas of northeastern iran. methods;the water microbial quality was determined in all villages (a population of 53047 people), in 3 rounds and based on 3 measurements, i.e. total coliform, fecal coliform, and heterotrophi...
We assessed the food safety knowledge and food handling practices of 23 food handlers in 2 hospitals in Alexandria, Egypt [Gamal Abdel Nasser (GAN) and Medical Research Institute (MRI)] before and after a food safety training programme, and also the bacteriological quality of patient meals and kitchen equipment. There was a significant improvement in all knowledge-associated parameters except f...
Background and purpose: Due to inadequate quantity and low quality of water resources in rural regions of Gomishan (Golestan province), local residents use cisterns for household water. Therefore, it is necessary to investigate the hygienic situation of these cisterns. Materials and methods: In this study, water samples were obtained from 31 villages using random sampling (two times; t...
There is currently no established bacteriological beach quality monitoring (BQM) program in place in Malaysia. To initiate cost-effective, sustainable bacteriological BQM schemes for the ultimate goal of protecting public health, policy decision makers need to be provided robust, indigenous empirical findings that validate appropriate water quality parameters for inclusion in such monitoring pr...
AIM To investigate bacteriological quality in organically grown leaf lettuce, including the presence of selected pathogenic bacteria, and to obtain information about organic lettuce production, including fertilizing regimes. METHODS AND RESULTS Altogether 179 samples of Norwegian organically grown lettuce were collected from 12 producers. Escherichia coli was isolated from 16 of the lettuce s...
Data from a study of five stations on the Spoon River, Ill., during June 1971 through May 1973 were analyzed for compliance with Illinois Pollution Control Board's water quality standards of a geometric mean limitation of 200 fecal coliforms per 100 ml. This bacterial limit was achieved about 20% of the time during June 1971 through May 1972, and was never achieved during June 1972 through May ...
Bacteriological quality of homologous breast milk Sir, In a recent report Carroll et al.1 showed that the bacterial colony counts of early drip breast milk did not differ from midstream samples and they concluded that early milk was suitable for milk banks and should not be discarded. We report our findings of 'significant' bacterial counts in early milk samples, since we were interested in the...
