GHP stands for Good Hygienic Practices, a foundational set of procedures every food business needs to follow to keep food safe. It covers things like the personal hygiene of workers handling food, proper cleaning and sanitising of surfaces that touch food, and controlling waste and pests around the facility. Since GHP forms the base layer on which more advanced systems like HACCP and ISO 22000 are built, its full form is Good Hygienic Practices.
