Hello,
There have been alot of voluntary recalls from several companies, because it is still unclear exactly what has caused the contamination. Contaminated wheat gluten has been identified, so anything with that ingredient may be unsafe. You can find the codes on the Ol'Roy recalls at the bottom of these lists: http://www.fda.gov/oc/po/firmrecalls/delmonte04_07.html, http://www.fda.gov/oc/po/firmrecalls/delmonte03_07.html, http://www.fda.gov/oc/po/firmrecalls/sunshinemills04_07.html. To stay updated on the recalls, refer to this site: http://www.fda.gov/oc/opacom/hottopics/petfood.html#recall.
I hope this helps.
