Quesadilla: what the available label data says

For a child with a dairy allergy, a traditional quesadilla is unfortunately unsafe. The primary ingredient that makes a quesadilla a quesadilla is cheese, which is a dairy product. In Mexico (MX), where quesadillas are a staple, the most common cheeses used are Oaxacan cheese (quesillo), Chihuahua cheese, or a blend of melting cheeses, all of which are derived from cow's milk and contain lactose and milk proteins. Even if you try to make a quesadilla without cheese, the term itself implies cheese, and many restaurants or street vendors may not understand or accommodate a strict dairy-free request, potentially leading to cross-contamination or the addition of dairy in other components like butter or cream used in preparation. It is crucial to avoid traditional quesadillas to protect your child from an allergic reaction.

Even seemingly simple quesadillas can contain hidden dairy. Some recipes might include butter for frying the tortilla, or dairy-based sour cream or crema as a topping. When ordering at a restaurant or buying from a street vendor in Mexico, it is essential to be extremely explicit about the dairy allergy. You must ask if the cheese is dairy-free (which is highly unlikely for traditional cheeses), if butter is used on the comal (griddle), and if any dairy is present in other toppings or sauces. Given the high risk, it is best to steer clear of quesadillas altogether and opt for other dishes that are naturally dairy-free or where dairy-free preparation can be guaranteed.
