Naturally occurring sulfites considered as allergens?

Dear all, in the one of our ingredients, we have naturally occurring sulfites (source onion & garlic). I wish to know if these forms can be considered as allergens? The supplier has not informed us regarding the concentration of sulfites in these products. Thanks and kind regards, Shakti.

Thanks & kind regards,
