I think businesses that sell food products should already track in detail what kind of wheat their suppliers provide.
Why? They know it's wheat. Why should they be able to track arbitrary characteristics of the wheat? It's like asking them to track which wheat is grown on Tuesdays, or which wheat is grown by Jews. Their system wouldn't be set up for it.
the obligation to provide that information doesn't imply that the government thinks I should care about it.
Containing peas is a subcase of a general requirement "list all ingredients". It certainly implies that consumers do and should care about the ingredients.
I don't think that trying to enforce labeling is the most straightforward way to deal with something that's illegal.
Using produce picked by illegal immigrants in your product is not itself illegal. Furthermore, it may be that the politicians in charge of the labelling laws are not the same politicians in charge of the border laws, so we might have lax border enforcement while labelling laws are enforced for real.
But anyway, that's fighting the hypothetical. If you wish, substitute some other politically charged trait that faces right-wing opposition; for instance "this produce comes from a company whose owner has had an abortion".

Supermarkets where I come from do check characteristics of ingridients like pesticide content. They generally care about providing quality products.
If a supermarket wouldn't do quality management of their suppliers I would consider that bad.

Basically: How does one pursue the truth when direct engagement with evidence is infeasible?
I came to this question while discussing GMO labeling. In this case I am obviously not in a position to experiment for myself, but furthermore: I do not have the time to build up the bank of background understanding to engage vigorously with the study results themselves. I can look at them with a decent secondary education's understanding of experimental method, genetics, and biology, but that is the extent of it.
In this situation I usually find myself reduced to weighing the proclamations of authorities:
