Heinz is a large food company, known around the world for tomato ketchup and for food in cans — soup, baby food, and baked beans (beans cooked in a tomato sauce). In English, people often say Heinz when they mean the ketchup: 'Pass the Heinz.' The name is a brand, not a kind of food; other companies make ketchup too, but Heinz is the one many families grew up with, especially in the US and the UK. The company is famous for an old slogan, '57 Varieties', which is why you still see the number 57 on the bottle. People sometimes stretch the name — 'Heinz 57' can mean a mixed-breed dog — though that is playful talk, not the food sense.
