HACCP audits are only obligatory once every year, but the frequency can vary. Internal audit can be done on a monthly/quarterly basis, where an external audit is typically done once a year, with high-risk operations or significant changes. Changes like new ingredients, new equipment, complaints, etc., provoke more frequent checks (quarterly, monthly, etc.) to ensure compliance and food safety continuity.
The best practice is to update the HACCP audit more often. But it mostly depends on some factors. So, in this article, we will answer your question on how often should a HACCP audit be carried out? We will also learn about the many types of HACCP audits and their importance. The HACCP certification process and how you can pass it will be discussed as well.
