Oregano is not an FDA-designated Top 9 allergen, so it does not have to be disclosed individually and may be a hidden ingredient under the term spices.
Additionally, the product may be manufactured on equipment or in a facility where peanuts and milk are also processed, a concern for cross-contact. Since precautionary allergen label (PAL) disclosures are entirely voluntary and there are no guidelines for how they should be written, the manufacturer is free to warn for sesame and not for peanuts and milk.
Remember: The absence of a PAL statement does not mean the product is safe from potential cross-contact!
