Ordering coffee on a plane might seem like a routine part of air travel, but there are several reasons why you might want to reconsider that choice. Here’s why experts advise against drinking coffee served on airplanes.
1. Water Quality Concerns
The primary reason to avoid coffee on airplanes is the water used to make it. Aircraft water tanks and plumbing systems can harbor bacteria and contaminants due to irregular cleaning schedules and potential for stagnant water. The water used for making coffee, tea, and other beverages may not be as clean as you expect, even if it undergoes some level of filtration or treatment.
2. Risk of Contamination
The water used in airplane coffee machines and storage tanks can be a breeding ground for bacteria such as E. coli and coliforms. These bacteria can survive even in water that has been treated with disinfectants. Inadequate cleaning and maintenance practices on aircraft can further exacerbate the risk of contamination.
3. Cleaning Practices
Airplane water tanks and coffee machines are not cleaned with the same frequency and rigor as municipal water systems or food service establishments on the ground. The complex plumbing systems of airplanes make thorough cleaning and disinfection challenging. As a result, residual buildup of bacteria, mold, and other contaminants can persist in the water supply.
4. Regulatory Oversight
While airlines are required to adhere to regulations regarding water quality on planes, oversight and enforcement can vary. The Environmental Protection Agency (EPA) and the Federal Aviation Administration (FAA) have guidelines in place to ensure the safety of onboard water systems, but compliance and monitoring may not always guarantee water purity.
5. Potential Health Risks
Consuming coffee made with contaminated water poses health risks, especially for individuals with weakened immune systems or underlying health conditions. Bacterial infections from contaminated water can lead to gastrointestinal illnesses, nausea, vomiting, diarrhea, and in severe cases, more serious health complications.
Alternatives to Airplane Coffee
If you’re looking for alternatives to coffee while flying, consider:
- Bottled Water: Opt for bottled water or beverages that come in sealed containers to minimize the risk of contamination.
- Tea Bags: Some passengers prefer using hot water from the flight attendant to steep their own tea bags, as the water is heated to a higher temperature that can potentially kill some bacteria.
- Prepared Beverages: Pre-packaged beverages such as canned sodas or juices are generally safe choices as they are sealed and less likely to be contaminated.
Bottom Line
While airlines take measures to ensure the safety of onboard water systems, the risk of contamination remains a concern when it comes to coffee and other beverages. To reduce the risk of exposure to potentially harmful bacteria, passengers may consider opting for bottled beverages or other sealed options while flying. By making informed choices about what you consume onboard, you can help minimize health risks associated with airplane travel.
