Joyce Farms is highly regarded for their sustainable agricultural practices, for their strict sanitation policies and commitment to all-natural breeding techniques, and for source verifying to family farmers. This is the beef we have ground and shaped into patties by Wonder Meats in Carlstadt, N.J., known for decades as the leading manufacturer of fresh ground beef and hamburgers. They are the first choice for chefs around the country because of their strict adherence to an old fashioned process - using a low-pressure chopping machine instead of grinding for better taste.
