An online course must be taken before taking our HACCP training. Follow these steps:

This training takes learners an average of 10 hours to complete, but please register at least 2-3 weeks before the DOH training to allow time for access and completion. Don't wait until the week of DOH training to sign up and take the online Cornell course.

2. Fill out our HACCP Training Registration Form (Word) and pay your fees by mailing a check (with registration form). The registration fee is $50 and covers the cost of materials given to each participant. The fee is non-refundable and only applies to the date you register for.
