Do this not make you sick? The coliform count is used to indicate the amount of fecal matter that there is to determine the sanitary quality of foods and water.
To make things worse, the EPA also found that of the 158 aircraft that they studied, two were positive for E. coli, a bacterium that can cause diarrhea and stomach cramps.
In response to these studies, the EPA changed their standards in 2009, forcing airlines to use water sources that follow the guidelines of the FDA (Food and Drug Administration). You should also disinfect the water and test it at least once a year.
Unfortunately, the new regulations may not have had the desired results yet. In 2012, the EPA conducted more tests and the results were similar. Around 12% were still showing positive for coliform, although only 0.5% contained E. coli, according to NBC 5.
If you think that none of this matters because heating the water will kill any disease, it may be mistaken.
“Heating the water could kill some of the agents”, commented Environmental Scientist Brenda Wiles. “But will not kill the vast majority“.
If you’re going to order a drink on an airplane, perhaps the smart thing is to opt for something that is bottled.
