Costco's famous signature hot dogs are made at their own Kirkland meat processing factories, which keeps costs down and ensures consistent taste and quality year after year.
While many Costco products are made by other brands and packaged with their in-house label, the company has its own food manufacturing supply chain for bestselling products.
For a long time, Costco's hot dogs were made by Hebrew National. However, as Costco grew, kosher meat suppliers decreased, and the price of Hebrew National's products went up.
As a solution, Costco operates multiple meat processing facilities in the U.S., making raw and cooked hamburger patties, meatballs, and other meat department favorites.
