Papa Murphy's Canadian Bacon

High histamine

Canadian bacon topping is high in histamine because the cured, smoked pork itself is high.

This is sold raw and you bake it at home, which is the freshest case on this whole list. Nothing sits in a warmer, and you control how long it waits between the shop and the oven. Refrigerate it as soon as you get home and bake it the same day, because histamine builds up as protein foods sit whether that happens in a kitchen or in your fridge.

Papa Murphy's Canadian Bacon topping is high in histamine. It is cured pork, and curing is exactly the kind of process that lets histamine build up in a protein rich food, so the topping arrives already high before the pizza is ever baked.

Why papa murphy's canadian bacon is rated high

Canadian bacon starts as lean pork, which on its own would be a much milder choice. The problem is what happens between the fresh pork and the topping bin. The meat is cured with salt, dextrose, and sodium nitrite and held through that process, and curing a protein rich food gives the specific bacteria that make histamine both the time and the material they need. Once histamine has formed during curing, it stays. Baking the pizza will not undo it, because heat can kill bacteria but it does not remove histamine that already formed. That is why this sits with cured and processed meats rather than with fresh pork.

What changes your risk

  • The curing is the whole story — the histamine here formed during the curing process, before the topping ever reached the store. There is no fresher batch of the same product that would land lower.
  • Sodium nitrite marks it as a cured product — it is on the ingredient statement alongside salt and dextrose, and it is part of what puts this topping in the cured meat category rather than the fresh meat one.
  • Baking does not lower it — the pizza goes through a hot oven, and that does nothing to the histamine already in the pork. A well done pizza is not a lower histamine pizza.
  • Sitting in the topping bin — cured meat is protein rich, so time at warm counter temperatures is a real concern for a food like this in a way it is not for a vegetable topping.
  • How much goes on — a heavier layer of the topping means more of the driver in every slice. Fewer pieces means less of it, though the topping itself stays high either way.

Lower-histamine alternatives

The lower rated protein option here is Chicken, which is the straightforward swap when you want a meat topping without a cured one. For flavor rather than protein, the Onion Mix and the Zesty Herb Blend both rate lower and give you savory depth without cured pork. The general principle is worth remembering beyond this counter: fresh cooked meat sits far lower than the cured, aged version of the same animal, so choosing Chicken over Canadian Bacon is the fresh versus cured decision in miniature.

How to lower the risk

Papa Murphy's is a build your own counter, so you are choosing toppings one at a time rather than accepting a fixed recipe. That works in your favor here. Ask for Chicken as your protein instead of the Canadian Bacon, and lean on the Onion Mix and the Zesty Herb Blend to carry the flavor. Since these pizzas are taken home and baked, a pizza built without cured meat also travels better from a general food handling standpoint. If someone else in your household wants the Canadian Bacon, it is worth ordering separate pizzas rather than a half and half, since toppings shift around during baking and slicing.

Common questions

Is Canadian bacon lower in histamine than regular bacon?

Canadian bacon is leaner, but leanness is not what drives histamine. It is still a cured pork product, and it rates high for histamine intolerance the same way other cured meats do.

Does baking the pizza reduce the histamine in the Canadian bacon?

No. Baking kills bacteria but does not remove histamine that already formed during curing, so the topping is just as high on a hot pizza as a cold one.

What topping should I pick instead at Papa Murphy's?

Chicken is the lower rated protein topping. The Onion Mix and Zesty Herb Blend also rate lower and add flavor without cured meat.

Why is cured pork high when fresh pork is not?

Curing gives histamine forming bacteria time to work on a protein rich food. Fresh pork has not been through that process, which is why the cured version lands so much higher.
