The intricacies of modern day food technology make it virtually impossible for anyone but an expert in the field to know whether a processed food is free of any trace of non-kosher ingredients. So all processed foods and eating establishments require certification by a reliable rabbi or kashrut supervision agency. Rabbi Brod specializes in supervising facilities, ensuring the highest standards are kept. If you know a company that would like supervision, feel free to contact Rabbi Brod at  209-952-2081.
