E coli definition

What is E. Coli, also known as Escherichia coli?

It is a common bacteria found in human and animal intestines. E. coli is a rod shaped bacteria cell. Majority of the time it's beneficial for the digestive system. However, there are a few strains or variations of this bacteria that cause adverse reactions. Specifically, the strain, O157:H7 produces a toxin called Shiga that damages the lining of the intestines. It is most often found in under cooked food such as hamburger, unpasteurized milk, and fresh produce, like spinach and lettuce.  

Health Affect of E. Coli

It causes diarrhea, stomach cramps, and/or nausea and vomiting. Because the toxin damages the lining of the intestines, in some cases the diarrhea is bloody. In severe cases, if the infected person doesn't recover within about a week, hemolytic uremic syndrome may develop which is life-threatening kidney failure. 

Those with weakened immune systems are more susceptible to contracting E. coli, such as young children and elderly. Those who take certain medications (i.e. Nexium, Protonix, Prevacid, and Prilosec) that affect the stomach acid levels can also contract E. coli more easily because the body's natural defense against bad bacteria are affected. For undetermined reasons, more E. coli cases happen June to September so the time of year may also be risk factor. 

The E. coli bacteria is highly contagious. It spreads from person to person easily. Washing hands is one of the best ways combat catching it.

How does E. Coli get in Your Water?

Human and animal feces is one of the main carriers of the bacteria. Unfortunately, more often than we'd like to think, water and food is contaminated by feces. (Ew. Gross). It only takes a minuscule amount of E. coli to cause adverse health issues. The contamination of drinking water can happen when not properly treated or sterilized. Waste water that contains human and/or animal stool goes downstream, which inevitably is upstream for someone else. This water can be used for irrigating crops and eventually ends up at the faucet in someone's home. Even if it goes through a water treatment plant E. coli bacteria can sometimes still survive. Tap water from a well has a higher likelihood of contamination because it doesn't go through as rigorous of sterilization as municipal water treatment plants. 

More often, people contract the bad strains of E. coli from contaminated food such as unpasteurized milk, soft cheese made from raw milk, unpasteurized apple cider, and undercooked meat.  People may also contract it by accidentally swallowing lake or pool water when swimming.  

How Berkey Removes E. Coli?

Before water ever enters the spigot that it comes out of it must pass through a complex filter with three key factors in it that trap, prevent, and neutralize any contaminants. The Berkey purification process uses microfiltration, adsorption, and ion exchange with removes 99.9% of all bacteria, including all strains E. coli bacteria. 

This is a great reminder to ALWAYS wash your hands after using the bathroom, changing a diaper, petting animals, and before preparing food. Always rinse or wash your produce before consuming--better yet, rinse your produce with Berkey water!
