Show DDT Is Net Always ysrmful to Animals Absorption or Licking Toxicity Overplayed When DDT fly sprays first became be-came available for farm buildings and livestock, there was considerable consider-able talk about sprayed animals being be-ing poisoned from absorption through the skin, or from licking one another, or licking the walls of buildings to which DDT had been applied. Evidence, however, indicates the danger of toxicity to animals has been overplayed. For instance, in Missouri last summer, a cow drank half a tubful of DDT barn spray L i S A: , V M while the farmer was tinkering with his sprayer and getting ready to spray his barn. The cow suffered no bad effects. At West Virginia university last year the dairy department threw caution to the wind and put 32 pounds of 50 per cent DDT powder in 100 gallons of water then sprayed cows with it. That figures out about 16 per cent for DDT. Most recommendations to date have been under 1 per cent for DDT water sprays on animals. "There were absolutely no harmful results" the head of the dairy department reported. re-ported. The DDT controlled flies, too. The spray was put on in May, and there were no flies on the cows until the middle of August. |
