It is also imperative that you make inquiries regarding the level of expertise and knowledge that the various agencies have about your particular industry. For example, if you are producing a food chemical such as citric acid or an amino acid, be sure that the Rabbi making the initial plant visit is familiar with industrial fermentations.
