There are a few good resources about what food can be brought back from Mexico with you:

• A brief article from the U.S. Customs and Border Protection website: "What are the general foods that can enter the United States?"
• Visit the USDA website and search the USDA's Fruits and Vegetables Import Requirements (FAVIR) Database of approved items.
• Call the USDA to find out specific information regarding what you would like to bring back into the U.S. at 1-877-770-5990 or 301-734-0814.
• Below is a list of items provided by the USDA and U.S. Department of Homeland Security, called Notice To Traveler, given to SENTRI card holders as a guideline. The list is not comprehensive, some items not listed may be prohibited from entry. The list is continuously updated by the appropriate government agency and the list below may not reflect those changes.
