E. coli - What You Need to Know and How to Test for it
What is E. coli and why is it a Concern?
E. coli, also known as Escherichia coli, are bacteria that reside in the intestines of both humans and animals. While most forms of E. coli are harmless and can even be beneficial for digestion and vitamin production, there are strains (commonly referred to as Pathogenic E. coli) that can cause severe illness in individuals.

These pathogenic strains can contaminate food and water sources posing a risk when ingested. Given the health hazards associated with E. coli infections, it's crucial for homeowners, businesses, healthcare facilities and local authorities responsible for drinking water to remain vigilant by testing for any signs of E. coli contamination. Early detection plays a role in preventing its spread and safeguarding people from falling ill.
How E. coli Spreads and Causes Illness
Poor hygiene often plays a role in the spread of E. coli especially when people neglect to wash their hands after using the bathroom.
E. coli can also be transmitted through consuming contaminated food or water. Meat may become contaminated during the slaughter or processing stages, while produce can be tainted if it comes into contact with feces from wild animals. Additionally, water can be exposed to E. coli through sewage leaks, runoff from animal agriculture or waste from swimmers.
Once the bacteria are ingested, it multiplies in the intestines and attaches itself to the wall using small finger like projections which causes inflammation to the lining of the intestines resulting in profuse diarrhea.
Other symptoms that may manifest include nausea, vomiting and fever. In these kinds of infection, E. coli can spread from the intestines into the bloodstream. This progression can lead to a condition known as Hemolytic Uremic Syndrome (HUS) is characterized by blood cell destruction and kidney failure. From 5% to 10% of individuals who develop HUS will unfortunately succumb to it. Timely treatment is crucial for which identification of E. coli through testing is necessary.

Different Types of E. coli. Pathogenic, vs Non-Pathogenic Strains
E. coli encompasses a range of variants numbering in hundreds; they fall into two groups: pathogenic strains capable of causing illness and non-pathogenic strains that do not pose any health risks.
There are the kinds of E. coli that cause illness.
E. coli O157:H7. This type leads to a serious condition characterized by bloody diarrhea and is responsible, for roughly 70% of pathogenic E. coli cases, in the United States.
- Non-O157 STEC - Shiga toxin-producing E. coli that cause similar symptoms as O157. Common serogroups include O26, O45, O103, O111, O121, and O145.
- Enterotoxigenic E. coli - Leading cause of traveler's diarrhea with watery diarrhea and abdominal cramps.
- Enteropathogenic E. coli - A common cause of diarrhea, especially in infants.
- Enteroaggregative E. coli - Can cause persistent diarrhea in children and travelers.
Non-pathogenic E. coli is a normal part of the intestinal flora. They help digest food, produce vitamin K, and prevent colonization by harmful bacteria. The presence of non-pathogenic E. coli does not indicate fecal contamination or health risks. Only pathogenic strains call for concern and disinfection measures.
Sources of E. coli Contamination in Homes and Businesses
E. coli can sneak into a home or business from a variety of sources, which underscores the importance of testing. Frequent trouble spots for E. coli contamination include the following issues.
- Food preparation areas where raw meat, eggs, or unwashed produce cross-contaminate other foods.
- Bathrooms. If toilets back up or leak, allowing bathroom bacteria into sinks and tubs. Diapers also harbor E. coli from baby feces.
- Private wells exposed to septic or sewer leaks, fertilizer run-off, or animal waste.
- HVAC systems if condensate pans become moldy, which can harbor E. coli.
- Daycares with diaper changes and bathroom accidents. E. coli easily spreads via unwashed hands.
- Hot tubs and swimming pools, if improperly chlorinated and contaminated by "poop accidents."
- Lakes, rivers, or ocean water near storm drains or sewage outlets.
Regular testing helps identify E. coli issues before major illness occurs. It also confirms disinfection efforts were effective if E. coli was found previously.

When to Test for E. coli - Risk Factors and Warning Signs
Certain situations call for proactive testing for E. coli even without serious symptoms. These high-risk scenarios include:
- Recent sewage backup, leakage, or septic issues.
- Repeated bouts of gastrointestinal illness at home, work, or daycare.
- Private well contamination discovered in the area.
- Food service business involved in an outbreak.
- Someone develops HUS or bloody diarrhea.
- After extensive flooding of homes or agricultural areas near wells.
- Water systems issuing a boil water advisory.
Children, elderly, pregnant women, and immunocompromised individuals are at highest risk if E. coli is present. Testing should occur onsite and offsite after issues are resolved to confirm E. coli is no longer present before giving the all-clear. People also need to watch for telltale signs of an acute E. coli infection. Look out for the following issues.
- Severe abdominal cramps and watery diarrhea, often turning bloody.
- Vomiting and mild fever.
- HUS symptoms like decreased urine output, fatigue, and bruising.
If such warning signs appear, prompt E. coli testing is critical to direct treatment and prevent serious complications. People also need to watch for telltale signs of an acute E. coli infection. Look out for the following issues.

Preventing E. coli Contamination and Recurring Outbreaks
An ounce of prevention is worth a pound of cure when it comes to E. coli. Preventative measures include:
- Careful handwashing with soap and warm water after using the bathroom, changing diapers, or before preparing food.
- Thorough cooking of ground beef and other meats to destroy pathogens.
- Keeping raw meat separated from ready-to-eat foods.
- Washing all fruits and vegetables thoroughly.
- Avoiding swallowing water when swimming in lakes or pools.
- Proper chlorine levels in pools and hot tubs.
- Fixing any sewage or septic issues immediately.
- Disinfecting areas testing positive for E. coli, focusing on surfaces touched often. Bleach solutions work well.
- Preventing exposure of private wells to animal waste and runoff.
- Address recurring E. coli with full investigations to determine the root cause.
Regular testing provides early detection so contamination can be addressed promptly before infections spread. Ongoing prevention measures also help avoid recurrent E. coli problems down the road.
The Importance of Testing for E. coli to Ensure Healthy Indoor Environments
E. coli testing provides crucial insight into the microbial landscape within a home or business. Finding E. coli contamination means pathogenic bacteria have been introduced and fecal contamination occurred. Without testing, this serious health risk remains invisible.
Proactive testing allows identification of E. coli hotspots so proper remediation can begin immediately. Follow-up testing confirms when the threat is neutralized. For high-risk settings like daycares, restaurants, and nursing homes, routine screening is key to protect vulnerable populations.
Testing also provides peace of mind after sewage backups, flooding events, gastrointestinal illness outbreaks, or other red flag situations. Once lab results come back negative for E. coli, people can breathe easier knowing their environment is safe again. The testing process empowers people to take control of their health by revealing microbial hazards.
In summary, E. coli testing is an essential tool for ensuring indoor environments remain free of dangerous pathogens. The testing allows issues to be tackled proactively before major illness can occur. By detecting contamination early and prompting swift action, testing offers protection for homeowners, businesses, and employees against these formidable bacterial foes.
