Legionella, an elusive bacterium, demands the utmost attention from the hotel industry due to its significant risk. Understanding the consequences of this bacterial intruder is crucial for ensuring the well-being of both guests and staff. Legionnaires’ disease, a severe form of pneumonia caused by Legionella, can lead to illness and, in rare cases, even death.

Legionella was first identified during an American Legion convention in 1976. While it does not pose a significant threat in natural environments, it thrives in poorly managed man-made water systems. Cooling towers, hot tubs, showers, sprinkler systems, and plumbing networks can provide ideal conditions for its growth, especially when temperatures range between 25-50°C (77-122°F). Stagnant water and insufficient disinfection measures contribute to its proliferation.

Legionnaires’ disease is contracted by inhaling water droplets contaminated with Legionella bacteria, which can occur during activities such as taking showers, using hot tubs, or being near sprinkler systems. It is important to note that person-to-person transmission does not occur. However, individuals with compromised immune systems, smokers, and those over 50 years of age are more susceptible to this bacterium.

Recognising the warning signs is crucial. Symptoms of Legionnaires’ disease include fever, chills, cough, muscle aches, and shortness of breath. Prompt diagnosis and treatment with antibiotics are essential for a full recovery.

Prevention is the key to mitigating the risk. The hotel industry should implement a robust Legionella risk management program to safeguard their premises and protect guests and staff. This includes maintaining stringent hygiene and disinfection protocols in water systems. Regular cleaning and disinfection of cooling towers, hot tubs, showers, sprinkler systems, and other water sources significantly reduce the risk of Legionella contamination. Effective temperature control will impede its growth. Designing water systems to minimise stagnation and promote water flow is important to prevent the bacterium from establishing a foothold.

To assist in these endeavours, Food Consulting Services (FCS) offers SANAS-accredited Legionella testing services. By partnering with FCS, hotels can benefit from expert consultation and risk auditing to develop comprehensive Legionella risk management programs tailored to their needs, ensuring a safer environment for all.
