The TB Outbreak at Maître: A Case Study in Public Health Response
The recent tuberculosis (TB) outbreak at the Maître food supplier in Oude-Tonge, Netherlands, has brought public health responses into the spotlight. Initially, the situation seemed alarming, with dozens of employees testing positive for TB. However, further investigation revealed that none of these employees were actively sick or contagious. This case study offers valuable insights into how public health agencies and private companies can work together to manage outbreaks effectively.
Initial Findings and Response
On Goeree-Overflakkee, two employees at a Maître facility were diagnosed with the active, infectious form of TB. The first case was reported to the local health department (GGD) at the end of last year, and the second case mid-January. Both individuals were immediately isolated. The GGD conducted an extensive contact investigation, testing 156 employees with a skin test. Initially, 85 employees tested positive, indicating possible exposure to the TB bacterium.
Further Investigation and Results
Follow-up tests, including lung X-rays and blood tests, revealed that none of the employees were infected with active TB. However, the presence of TB antibodies in some employees indicated past exposure. This is particularly relevant given that many of Maître’s employees come from Eastern Europe, where TB vaccination is more common. This meant that their skin tests could have shown a positive result due to the presence of vaccines antibodies, not active infection.
The Source of the Infection
The regional broadcaster Rijnmond reported that the person who tested positive for TB in mid-January was identified as the source of the infection. This individual had been working at the company for some time, making the need for ongoing vigilance clear. The GGD will continue investigations to detect any further infections, with research beginning mid-March to allow for the 8-week incubation period and to measure immune reactions effectively.
The Role of Public Health in Preventing Spread
The GGD’s prompt action demonstrated the importance of thorough contact tracing and testing. Although TB is relatively rare in the Netherlands—with only 710 reported cases in 2023—such outbreaks highlight the need for vigilance. The GGD’s approach included initial skin tests, followed by more comprehensive tests, ensuring that only those who might be at risk received further medical attention from the GGD.

This case study underscores the importance of continuing public health education about TB. It also emphasizes the need for health agencies to stay ahead of potential outbreaks, especially in locations where there may be a higher concentration of individuals from regions with higher rates of TB vaccination and exposure.
Moving forward, it’s crucial for companies like Maître to keep protocols in place for ongoing health monitoring and the rapid response in future outbreaks.
Pro Tips for Preventing and Managing TB Outbreaks
Regular Health Checks: Companies should consider periodic health checks, even if there’s no current outbreak. This can help detect potential risks early.
Employee Education: Ensure that employees are well-informed about TB, how it spreads, and the importance of reporting any symptoms promptly.
Continual Training: Keep medical personnel and supervisors trained in outbreak management procedures. This ensures a swift and effective response when needed.
Did you know?
TB, despite being curable, remains a significant public health concern. Globally, approximately 10 million people fall ill with TB each year, and around 1.5 million die from the disease. Early detection and treatment are essential to controlling its spread.
FAQ
What are the symptoms of TB? Early symptoms of TB include a persistent cough, fever, night sweats, and weight loss. In some cases, TB can also infect other parts of the body, leading to additional symptoms.
How is TB treated? TB treatment typically involves a combination of antibiotics. The standard treatment regimen lasts at least 6 months. Adherence to treatment is crucial to prevent drug resistance.
How can TB be prevented? Prevention strategies include early detection and treatment, as well as preventive therapies for individuals at high risk, like those in close contact with someone who has active TB.
Can TB spread through food? No. Tuberculosis is not transmitted through food, drink, or touch. It spreads primarily through the air when an infected person coughs, sneezes, or speaks.
