Buildings and processes that affect food safety and quality should take place under controlled environmental conditions. Parameters such as temperature and humidity should be established in advance and applied correctly. Process parameters essential to product safety and quality, such as temperature, time, pressure, and chemical properties, should be monitored and recorded regularly or continuously.
When air handling or cooling is required, the equipment used must be properly maintained and regularly cleaned. Air circulation should not adversely affect product safety or quality. An alarm system and an effective emergency plan must be available in case of malfunctions or deviations in temperature to ensure product safety. Dust extraction must be available in areas with high dust release.
The water supply must consist of potable water of suitable quality at the point of use, be present in sufficient quantity, and apply to hand hygiene, cleaning, disinfection, and to steam or ice that has direct contact with food or packaging, among other things. The quality of this water (including recycled water) must be regularly monitored based on a risk assessment. Non-potable water used in the process must not pose a contamination risk and must be transported through separate, clearly marked pipes.
