Environmental Testing & Plant Hygiene Monitoring

Environmental Microbiology Testing 

Manufacturing under hygienic conditions is essential to avoid microbiological problems and ensure that products consistently meet required quality standards. We offer the following testing to support routine plant hygiene monitoring and the investigation of microbiological issues. Our in-house environmental lab testing methods based on ISO 18593 covered by our CLAS scope.

Swab testing for bacteria, yeasts and moulds
Swab testing for specific micro-organisms, e.g.

• Enterobacteriaceae
• Coliforms/E coli
• Pseudomonas spp
• Staphylococcus aureus
• Presumptive Salmonella spp
• Presumptive Listeria

Hand and clothing swabs
Exposure plates for air monitoring

• This will consist of sending you sets of pre-poured plates - 2 per location: 1 plate for bacteria and 1 plate for yeast & moulds.
• These plates will need to be exposed for 60 minutes then returned to us for reading and interpretation.
• We apply pharmaceutical Class D limits for non-sterile manufacture or, we can apply any specification you require.

Bacterial identification
Water analysis

Monitoring the Environment

At Donnington we understand the critical role microorganisms play in our environment. Environmental microbiology testing provides valuable insights into the presence and activity of microbes in air, water, and various pieces of equipment and surfaces. This knowledge is essential for safeguarding public health, ensuring product safety, and maintaining GMP.

What is Environmental Microbiology Testing?

Environmental microbiology testing utilises techniques to identify, quantify, and assess microorganisms within environmental samples. These tests can help us detect harmful pathogens, spoilage organisms and evaluate the overall microbial levels.

This can take place on samples from Deionised water plants, factory, manufacturing vessels, filling machines and even outside spaces including lakes.

We can help you set up sampling schedules along with monitoring for trends. Covering air monitoring, surface swabbing and hand swabbing.
