Environmental monitoring in the production plant

Environmental monitoring includes checking the microbiological purity of air and surfaces from external surfaces of technological equipment and equipment, as well as wall and floor surfaces at designated control points. Equipment is equipment located in rooms (tables, cabinets, scales, etc.) and external surfaces of technological devices.

Microbial contamination of the air

In industrial plants, the purity of the air depends on the sanitary condition of the production rooms. The season of the year and the humidity in the rooms have a big impact on the degree of infection. Air is not an environment suitable for the development of microflora, it is a carrier through which microorganisms spread. Micrococcus, Sarcinia microorganisms can be found in the air most often; Achromobacter; bacillus; Rhodotorula; Torulopsis; penicillium; aspergillus; Mucor.

We check the microbiological purity of the surface using the contact method and the swab method. The contact plate method is used to test dry, flat, even surfaces. On the other hand, the swab method is most often used to check the cleanliness of the surface of hard-to-reach, curved, wet places, e.g. crevices.

When monitoring the microbiological purity of the production environment, it is also worth paying attention to the compressed air used in the plant. Compressed air is used in almost every production, either by supplying production equipment or as a means of removing mechanical impurities. Lack of control over the purity of this medium in production processes can cause financial losses and pose a threat to product safety. The pharmaceutical, cosmetics and food industries require the use of high-purity compressed air. Therefore, it is important to include the examination of the microbiological purity of compressed air in the environmental monitoring plan, because without proper purity control, we do not have detailed information about the quality of the medium used.

Establishing an appropriate plan for monitoring environmental conditions in a production plant is one of the most important elements in obtaining high-quality products, and thus safe for the consumer. Systematic testing as part of the control of production conditions may allow timely detection of the source of infection and take action to eliminate potential infections in production at an early stage, and thus prevent the production of poor-quality products that may bring both financial and marketing losses.

How is the cleanliness of employees' clothes and hands assessed?

The cleanliness of the worker's clothing can be assessed by taking samples from his abdomen, chest, forearm and any other pressure points (elbows or knees). On the other hand, the cleanliness of the worker's hands must be tested by taking a sample from the inside of the hands (distal along the fingers, around and between the fingertips, and along the palm prints). In both cases, the contact plate or swab method can be used.

Every step of food production involves making high-risk decisions. They often require limited information and strict deadlines. Consumer safety, brand reputation, hygiene monitoring and a good risk management system are important. Food business operators should also decide how often they will sample and test the environment at their production sites as part of HACCP-based procedures.

Environmental monitoring in public facilities

Air-conditioning systems are a frequent source of microbiological contamination, therefore, in accordance with EU recommendations, in rooms to which air is supplied by air-conditioning, its microbiological purity should be regularly checked.

Particularly dangerous to our health are fungal spores and pathogenic bacteria, multiplying in humidifiers and on filters of air conditioning systems. Insufficient ventilation of rooms can contribute to the accumulation of a large number of pathogenic microorganisms that cause numerous infections in people staying in them.

Contaminated air conditioning may cause irritation of mucous membranes and allergic reactions such as runny nose, conjunctivitis, dry eye syndrome or cough. Legionella infection can also occur.

Another source of microbiological hazards are rooms without air-conditioning, where there are more children or the elderly, e.g. nurseries, kindergartens, schools, health care facilities, nursing homes, etc. With insufficient ventilation of such rooms, they also become a habitat for pathogenic microorganisms that can cause numerous infections.

One of our specializations is Environmental Monitoring in the field of air, surface and compressed air testing.
