Bacteria Testing We offer various bacterial analytical services and tests at Mold & Bacteria Consulting Laboratories (MBL). We can test air samples (taken by an RCS sampler or an Anderson sampler), surface samples (taken by culture-swabs), and water samples, as well as many other types of samples. If you have a question regarding a particular […]

Troubleshooting Microbial Contamination In An Industrial Environment
Processing industries such as pharmaceutical, personal hygiene and beauty products, food (including dairy) have microbial contamination control procedures in place. Regular hygiene monitoring of a plant and equipment, and microbiological sampling of products and raw materials are invaluable in detecting potential sources and routes of contamination. Contamination especially in food industry can result to not […]
Interpreting Numerical Data of Viable Airborne Mould Samples
Another article on airborne mould samples provides guidelines for interpreting numerical data of viable air samples. To see the guidelines for non-viable air samples click Guidelines for Interpreting Non-viable Air Samples. The guidelines may be used to decide whether further investigations are required after initial investigations. As was indicated in the last Issue, numerical laboratory […]
Common Building Molds and Their Hazard Classes
Building molds are common on damp materials with a water activity value equal to or greater than 0.90. Building molds and yeasts such as strains of Aspergillus fumigatus, Trichoderma spp., Exophiala spp., Stachybotrys spp., Phialophora spp., Fusarium spp., Ulocladium spp., and yeasts such as Rhodotorula spp. grow well on very wet building materials. Materials with a water […]
Dampness, Mould, House Dust Mites and Allergy
The risk of asthma, allergic rhinitis, and atopic (hereditary) dermatitis is higher in damp buildings than non-damp buildings. However, dampness itself may have no or little direct effect to allergy development. Dampness only favours proliferation of biological and increased emission of chemical pollutants. A strong association has been found between exposure to visible mould and […]
