An internet search resulted in Master Bond's food safe adhesives/epoxies that are FDA approved for the food industry. http://www.masterbond.com/properties/food-safe-adhesives-sealants-coatings-encapsulation-compounds
According to the website, products EP30HT or EP30HV would be appropriate in this instance. There was no supplier listed for NM but you may be able to purchase from the website: http://www.masterbond.com
If considering purchasing a product, it is suggested that you ask the professionals using  the <personal data hidden> Help number, or sending an email using the "Contact Us" link provided on the home page.
Additionally, there are suppliers found on Amazon.com (search using "food grade epoxy glues) - Master Bond was not listed.  If considering purchasing any of these products, review the product fact sheet to make certain the bond withstands high heat and is food grade. Beware that there are many glues that will work but have not been tested for food use.
