One of the biggest risks in the production of medicines and sterile products is related to things you cannot see with the naked eye. Microbes can contaminate a product without any obvious warning signs, potentially leading to batch rejections, recalls, and risks to patient safety.
– These are risks that can have serious consequences if monitoring is not carried out systematically, says Medimo’s Quality Expert, Qualified Person (QP), Sanna Tuhkala.
Microbes such as bacteria, molds, yeasts, and spores are naturally present in the air, on surfaces, in water, in people, and in raw materials. They can easily enter production areas from the outside environment. A single unnoticed bacterium can multiply rapidly under the right conditions and spoil an entire batch of products.
Some microbes release endotoxins when they die, which are toxic compounds. Biofilms, which are layers of microbes that form on surfaces, also make cleaning more challenging.
– Microbiological monitoring is essential to prevent microbial contamination, ensure product quality, and protect patients, Sanna Tuhkala explains.
Microbes can travel along many pathways
A key part of microbiological monitoring is identifying and controlling all possible sources of contamination. In GMP environments, microbes can enter production through surprisingly many routes: from the air, surfaces, equipment, and personnel.
Raw materials, water systems, ventilation systems, and packaging materials can also be sources of microbes if they are not carefully monitored.
Systematic monitoring
Microbiological monitoring involves careful observation of the environment, personnel, and materials. It also ensures that processes work as they should.
- Environment: The microbiological cleanliness of cleanrooms is monitored regularly using air samples
- Surfaces and personnel: The cleanliness of surfaces, hands, and protective clothing is checked through sampling to ensure that microbes do not enter the process
- Water systems: The microbiological quality of water is monitored because contaminated water can spread microbes into production
- Sterilization and cleaning: Process effectiveness is monitored using biological indicators, and any issues are corrected quickly
Maintaining expertise is key
If monitoring shows that something is not within the set limits, action is taken right away. The issue is recorded, the reason is looked into, and steps are taken to fix the problem and stop it from happening again. This may mean cleaning more thoroughly, stopping production for a while, or training staff further.
Microbiological monitoring is a crucial part of producing safe medicines. By being careful, following clear procedures, and reacting quickly to any problems, a high-quality product is made.
– When microbiological monitoring is carried out carefully and consistently, the production environment remains controlled, products meet quality standards, and patient safety is ensured, says Sanna Tuhkala.
