In addition to assuming the role of a traditional food bank, St. Mary's also runs its own food pantry, allowing people to get food directly from their warehouses. St. Mary's frequently offers "mobile" food pantries — semi trucks filled with food products — in various locations throughout Arizona. These mobile pantries normally run on regular schedules, but they have also been dispatched for special occasions. During the 2018–19 United States federal government shutdown, for example, St. Mary's held a mobile food pantry to provide food for local TSA employees who were working without pay.
