The answer is yes. Production results usually improve after the implementation of good hygiene plans. Doubts about cleaning and disinfection may occur after a lot of effort has led to no observable effect. However, lack of effect is often due to faults and oversights during one or more of the disinfection tasks.
There is a whole list of factors that must be respected in the practical performance of chemical disinfection before an observable effect can reasonably be expected. It demands a thorough knowledge of the disinfectants used and considerable precision in the performance of the different tasks.
The commonest reasons for disinfection failure are:
• The use of an unsuitable or poor quality product for the task
• Lack of contact between the agent and the micro-organisms (often due to
shortcomings in cleaning and application, especially achieving good deposition,
coverage and penetration
• Lack of knowledge about or regard for, the right conditions
• De-activation of the disinfectant due to residues of organic matter
or incompatible detergent
• Using the wrong concentration of product
• Performance of the disinfection taking place at a too high or too low temperature
• Too short exposure time caused by rinsing off too early because a product is a
corrosive or using slow-acting products
that have dried before the effect is achieved.
