In many regions where drinking water supply is intermittent and unreliable, households adapt by storing water in cisterns or rooftop tanks. Both intermittent supply and stored water can be vulnerable to contamination by microorganisms with deleterious health effects. The Guadalajara Metropolitan Area is a rapidly growing urban center with over five million residents where household storage is nearly ubiquitous. This pilot study was conducted in July 2018 to examine the microbiological quality of drinking water in Guadalajara. Samples were tested for free available chlorine residual, total coliform bacteria, and E. coli. A survey on access to water and public perspectives was also conducted. Water exiting rooftop tanks exceeded regulatory limits for total coliform levels in half of the homes studied. Piped water arriving at two homes had total coliform levels that far exceeded regulatory limits. No E. coli were detected in any of the samples. Only 35% of homes had a chlorine residual between the recommended 0.2 and 1.5 mg/L. Many homes reported unpleasant odors and colors. Only 7% of residents drank the piped water. Future studies are needed, especially during April and May when many homes reported a higher disruption to water service.

Background: Bottled drinking water has become popular for consumption by customers. Bottled drinking water with pathogenic microbiological contamination is a public health concern. This study aimed to describe the current situation of microbiological contamination in bottled drinking water products, food safety conditions and some influencing factors in production facilities in Hau Giang province in 2020. Methods: A cross-sectional study has been conducted in 2020 using quantitative and qualitative methods. The evaluation was carried out at 54 bottled drinking water production facilities, 108 workers/owners and 54 samples collected from facilities for microbiological analysis in the province. In-depth interviews were conducted with local government officials on food safety, two owners of facilities and two workers. Results: It showed that the proportion of microbiological contamination in bottled drinking water accounted for 18.5%, of which P. aeruginosa contamination was 18.5%; and Coliform contamination was 3.7%; No drinking water samples were contaminated with E. coli. 79.6% of facilities met general food safety conditions. There were several factors affecting the proportion of microbiological contamination of bottled drinking water as follows: Bad compliance with food safety in production for the sake of profit by workers, affecting the quality of products such as trash cans without lids; No sterilization treatment before filling; Non-sterilization in filling room. Non-monitoring of UV lights for replacement; No regular cleaning of water pipes, tanks, and discharge valves; Difficulty in state management of food safety for facilities of bottled drinking water production, such as insufficient manpower, lack of equipment and funding for activities. Conclusion: The quality of bottled drinking water in Hau Giang province was not good. The important factors affecting the contaminated bottled drinking water products were identified. We recommend that: management agencies should frequently conduct sudden inspections and supervisions of facilities with no ensured food safety and strictly handle according to regulations. Owners of bottled water facilities should voluntarily comply with food safety. This study is particularly concerned with ensuring food safety conditions in the production of bottled drinking water to prevent products from microbiological contamination.

Sachet Water

Abstract Sachet water is one of the primary sources of drinking water in rapidly growing countries. A study to assess the microbiological quality of sachet water in 21 different brands was conducted in Ghana. Culturable total coliform was positive in 87% of the samples collected, where Escherichia coli colonies were absent. The analysis of quantitative polymerase chain reaction results indicated the presence of E. coli genes in 44.6% of the samples, with the highest concentration up to 3,166 CCE/100 ml. Microbial source tracking analyses showed that the source of E. coli genes did not originate from sewage contamination because the human-associated HF183 marker was not detected. Of the 175 samples tested, 71% did not mention any water treatment before filling the packages. These results suggest non-human sources of contamination, such as biofilm formation in the pipelines used to fill these packages due to poor disinfection. Our study shows an urgent need for increased regulation and standardized manufacturing of sachet water to ensure safe drinking water.

Quality Of Milk

In order to protect the hygienic quality of milk and nutrition of the dairy farm, an additional solution to milking hygiene is to control the contamination of the feeders environment. The effectiveness of an FTCMR (DeLaval) PVC feeding table cover on the microbial count was estimated by comparing the mesophilic aerobic bacteria, total coliform, E. coli and butyric spore counts between concrete feeding places (control) and another with the cover. This was done between October to January in a semi-intensive milk production system in Cunco, IX Region (Chile). Sterile swab were taken in areas of 10 cm2 and all counts were performed according to standards methods. Significant differences were obtained between the feeding places according to surface area (p 0.05), in all counts of indicator microorganisms. However, there were no statistical differences (p 0.05) between counts per month of sampling, except for the E. coli indicator (p = 0.001). In conclusion, the presence of the cover would positively influence the reduction of indicator microorganisms at the feeding level between October to January, which would protect the quality of the forage, and the hygiene and duration time of the milk.
