CAG Flags E. Coli In Railway Drinking Water: What Are The Health Risks?

A recent report by the Comptroller and Auditor General of India (CAG) found E. coli bacteria in drinking water from water coolers at several major railway stations across the country.

The report also flagged unhygienic conditions in railway washrooms and other passenger amenities. The audit found that 458 of the 512 stations examined — more than 89 per cent — did not meet prescribed standards for minimum essential amenities.

"Bacteriological analysis of drinking water was not carried out at 59 stations over six zones," the CAG said in its report, Passenger Amenities and Sanitation at Non-Suburban Railway Stations in Indian Railways, tabled in Parliament on August 12.

Water samples from coolers tested positive for E. coli at two stations in Southern Railway, one in South Central Railway, four in Central Railway and one in Eastern Railway.

The report also found total coliform bacteria, including E. coli, in tap water samples collected from platforms at several stations during 2022-23 and 2023-24.

Following the findings, Railway Minister Ashwini Vaishnaw has directed immediate steps to improve the safety of drinking water at stations.

The Railway Ministry said a new "tank-to-tap" filtration system would be installed at around 20,000 locations, including water coolers. The measures include replacing water tanks, regular water-quality testing at source and outlet points, centralized monitoring, accountability, and scheduled cleaning and maintenance of storage tanks.

Escherichia coli, commonly known as E. coli, is a group of bacteria that normally lives in the intestines of humans and animals. 

<em>HealthandMe</em> spoke to Dr. Pawan Kumar Goyal, Senior Director - Internal Medicine, Fortis Hospital, Shalimar Bagh, about E. Coli infection, its symptoms and how to prevent it. 

Dr. Pawan Kumar Goyal explains, "Most E. coli strains are harmless and are part of the normal bacteria present in the gut. However, some strains can cause infections, particularly when they enter the body through contaminated food or water."

<h2>What Happens During an E. Coli Infection?</h2>

Dr. Goyal says, "The presence of E. coli in drinking water is an important indication of faecal contamination. It suggests that the water may have come into contact with human or animal waste and may contain other disease causing organisms as well."

Harmful E. coli strains most commonly affect the digestive system, causing diarrhea, abdominal pain, and gastroenteritis. Some strains can also cause urinary tract infections.

Certain strains produce Shiga toxin, which can cause serious complications, including kidney damage, particularly in children and older adults.

<h2>Common Signs of E. Coli Infection</h2>

Symptoms can vary depending on the strain and the part of the body affected. Dr. Goyal says the common gastrointestinal symptoms include:

<ul><li>Diarrhoea, which may sometimes be severe or contain blood</li><li>Abdominal cramps and pain</li><li>Nausea and vomiting</li><li>Fever and weakness</li><li>Reduced appetite </li></ul>

Watery diarrhea is often one of the earliest symptoms of E. coli infection of the gastrointestinal tract.

Talking about the treatment for E. Coli infection, Dr. Goyal explains, "Treatment depends on the strain of E. coli and the severity of infection. Adequate fluids and electrolytes are important in most cases. Antibiotics are not appropriate for every E. coli infection and should only be taken following medical assessment, as certain infections may worsen with inappropriate antibiotic use." 

Not every E. Coli infection turns severe. However, certain symptoms must be addressed clinically as they could lead to complications. 

Dr. Goyal says, "For most healthy adults, the infection may settle with appropriate fluid replacement and supportive care. However, severe diarrhoea can cause dehydration, which can become dangerous if not treated in time."

The expert also spoke about serious complications from E. Coli infection that could lead to renal damage. 

He says, "Certain E. coli strains can also cause haemolytic uraemic syndrome, a serious complication that can affect the kidneys. 

The expert also said that young children, older adults and people with weakened immunity may be at greater risk of complications. 

He adds, "Persistent diarrhoea, blood in stools, high fever, reduced urination, dizziness or signs of significant dehydration require prompt medical attention. Early recognition and appropriate treatment can prevent complications."

<h2>How To Protect Yourself From E. Coli?</h2>

E. coli can spread through contaminated food, water and fecal matter. Basic hygiene and safe food practices can help reduce the risk.

Dr Goyal recommends, "Prevention depends largely on maintaining good hygiene and ensuring access to safe drinking water. Hands should be washed thoroughly before eating and after using the toilet. Water from an uncertain source should be avoided, and properly treated or boiled water should be used where safety is in doubt." 

<strong>Maintain Hand Hygiene: </strong>Wash your hands with soap and water for at least 20 seconds before eating or cooking and after using the toilet, changing diapers or handling animals.

<strong>Practice Safe Food Handling: </strong>Keep raw meat separate from ready-to-eat foods. Use separate utensils and cutting boards, and clean kitchen surfaces thoroughly after handling raw meat.

<strong>Cook Food Thoroughly: </strong>Cook ground meat to at least 160°F (71°C) and poultry to 165°F (74°C). A food thermometer can help ensure food reaches a safe temperature.

<strong>Wash Fruits and Vegetables: </strong>Wash produce under running water before eating, even if you plan to peel it.

<strong>Choose Safe Drinking Water: </strong>Drink pasteurized milk and juices and use boiled or treated water. Avoid unpasteurised products and untreated water, which can carry harmful E. coli strains.
