Environmental and Health Concerns

Big Mac, along with many other McDonald's products, was first served in a collapsible cardboard container that was changed to a "clamshell" style, polystyrene foam container in the late 1970s. Polystyrene foam containers were phased out beginning in 1990, due to environmental concerns. On October 1, 2018, McDonald's announced that it would remove all artificial preservatives, flavors, and coloring from the Big Mac.

The famous Big Mac Sauce

Big Mac Sauce is delivered to McDonald's restaurants in sealed canisters designed by Sealright, from which it is meant to be directly dispensed using a calibrated "sauce gun" that dispenses a specified amount of the sauce for each pull of the trigger. In 2012, McDonald's executive chef Dan Coudreaut released a YouTube video revealing the recipe of the sauce. It consists of store-bought mayonnaise, sweet pickle relish and yellow mustard whisked together with vinegar, garlic powder, onion powder and paprika. In 2018, McDonald's revamped the sauce by removing potassium sorbate, sodium benzoate, and calcium disodium EDTA. The sauce is occasionally available for purchase on its own for a limited time, which first occured in 2015.
