As a general rule, it’s best to maintain a controlled environment in growing and
processing areas whenever possible. This means ensuring that the humidity levels are
regulated, so as not to create conditions where bacteria and other pathogens can
thrive. Adequate air filtration is also essential to prevent the formation of
micro-climates, which can act as breeding grounds for pathogens like powdery mildew.
When designing your facility for optimal infection prevention, it’s also important to
minimize the potential for cross-contamination from dirty areas into production rooms.
This can be accomplished in part by having a dedicated room where people can enter to
remove dirty footwear and clothing, acting as a barrier between the outside
environment and the production areas. In addition, the use of personal protective
equipment (PPE) such as shoe covers, coveralls and hair covers are important in
ensuring that contamination by people entering the production areas is kept to a
Another factor to consider is plant movement: limiting the movement of plants,
wherever possible, is a good practice to lower the risk of disease transmission
between plants. Ideally, your facility will be designed to ensure that unnecessary
plant movement is eliminated.
