Biofilm Testing, Inspection, Validation and Spray Coverage Testing

Bio-film viewed under ultraviolet lightSources of contamination in food processing environments can be caused by a number of various variables, one being is insufficient cleaning and poor vessel design leaving biofilm / bio-fouling residues on internal surfaces in finished process tanks, silos, processing vessels, spray dryers, storage vessels and process pipework.

Independent Integrity Inspection Limited (INDEi) offers the facility to highlight areas of concern within minutes compared to other methods without the need for dyes or chemicals.


Using state of the art technology and experienced technicians, a prompt detailed survey will be conducted detailing areas that are not being cleaned properly due to poor CIP design / cleaning which require further hygienic actions to be taken.

The area(s) of concern can be viewed by all concerned parties in "real time" and further action plans can be formulated to combat the pathogen risk.

This method of detecting biofilm / bio-fouling residues can form a crucial part of any "Hazard Analysis and Critical Control Points (HACCP)" programme.
