Which group of bacteria E. coli? Intestinal bacteria are commonly found in soil, on plants and in surface waters. They also live in the intestines of warm-blooded animals and humans. Some strains of E. coli bacteria group can be stored in soil and water for a long period of time. Koliformnyh bacteria are unlikely to cause illness in most people, however, as the intestinal bacteria often associated with sewage and surface waters, the presence koliformnyh bacteria in water indicates that other disease-causing organisms (pathogens) may be present in water source or distribution system. There are three different groups of bacteria, Escherichia coli, and each has different levels of health risk:
Total E. coli bacteria are commonly found in the environment and are usually harmless. If only the total E. coli bacteria found in water, the source is probably environmental and faecal contamination is unlikely. If pollution can enter the system, however, that suggests that may be a way for pathogens to enter the system. It is therefore important to determine the source and solve the problem. Fecal bacteria Escherichia coli is a subgroup of the group of intestinal bacteria group. They are found in large quantities in the faeces of animals and humans. The presence of fecal intestinal water in the sample often indicates recent fecal contamination - meaning that there is great risk that pathogens are present than if only total koliformnyh bacteria were detected. E. coli
is a sub group of the intestinal fecal. Most E. coli are harmless and are also in large quantities in the feces strattera 10mg of people and warm-blooded animals. Some strains, however, can lead to disease. Some of these common symptoms of water are diarrhea, vomiting, headache, seizures (acute gastrointestinal illness). The population of high risk for this disease are: the very young, very old, and persons with weakened immune systems. The presence of E. coli in drinking water sample almost always indicates faecal contamination of water, and outbreaks of E. coli that typically receive much media attention. Many food outbreaks were caused particularly dangerous strain of E. coli known as E. coli 0157: H7, which can lead to serious illness or death. The provisions of Escherichia coli
This drinking water regulations of public water supply (EPA) and bottled water (FDA) are revisions (Ground water amendment Rule) for improved detection and prevention of contamination of E. coli both types of drinking water. When fully implemented, the corresponding E. coli maximum levels of contamination are: not more than 5% of positive samples of E. coli from municipal water supply samples of more than 40 times per month (the same as the current standard EPA); zero positive E. coli samples of finished bottled water product or its source of water (zero tolerance FDA standards). Violation of the standard E. coli for public water supply deficit requires correction and warning the public and responsible authorities. Manufacturer of bottled water in violation of the standard E. coli will not be allowed to produce finished products to the market or using contaminated source until violation is not corrected. In addition to public notice, product recall contaminated bottles of water from fields and destruction of products is required. Jack West is the Chairman of the Board of Trustees of drinking water research fund (DWRF) in Alexandria, Virginia. With over 30 years experience in bottled water, it is now Adviser of drinking water quality. City of Lacey, MI
