Will eating uncooked yeast make people sick? Is Vegemite uncooked yeast?

We wanted to represent Australia at an event, and decided to make Vegemite for about 200 people. The recipe we found:
2 small onions
2 Tablespoons butter
2 Tablespoons dried
bread crumbs
60 g fresh yeast
¼ Liter milk
½ Tablespoon Majoram (a spice)
Dice the onion finely, fry in butter. Stir in yeast and breadcumbs, cook until yeast begins to brown. Add milk, stir, and allow mixture to boil, then remove from heat.
Crumble and add Majoram.

Wouldn’t the yeast make people sick?
