re: chick edema disease

[Tom Webster <twebster@bu.edu>]

	Regarding Ralph Ryder's question. I'll have to check about the
Texas event you describe.
	There have been a number of episodes of chick edema disease in the
United States, going back as far as 1957 in the southeastern US. PCBs were
implicated in at least one episode, "toxic fat" in another. If I remember
correctly, the toxic fat had high dioxin levels, and may have been due to
pentachlorophenol treated hides rendered into the feed.  Millions of
chickens were also effect in the Yusho incident.
