crisco

Question

i was in the store and notice butter-flavored crisco. in the ingredinets list there is no dairy at all only "artificial butter flavor". however the product is listed OU-D. I called crisco and they said that there is a trace amount of dairy in the "artifical butter flavor". Is this product dairy at all? ( i have not determined if the trace amount of dairy is for taam - probably not since it's trace.) Thank You Mark
