You could probably find a way to do the necessary training online.
Alchemy Academy is pretty big in food industry for trainings.
If you prefer an in person class because you learn and comprehend information better that way, have your consultant provide you a list of upcoming training days in your area. If they just suggested to get certified but not offer any content to back it up, to me, that is (pardon my french) half-assing a job. They shouldn't suggest something without having the necessary information to back it up or provide information on it.
