I have a question about implementing allergen program for suppliers and customers who don't have allergen program. One of our biggest customer does not consider as celery seeds, mustard seeds, tree nuts as allergens although they have all kinds of certifications. All of their raw material (including non allergen raw materials) comes to us for processing and packaging. Should we treat all of their products as allergens since there is chance of cross contamination?
I am wondering what percentage of population are allergic to celery, mustard and other products? Isn't it too much regulations for small manufacturers?
