The recent cases of three local infants born with severe birth defects and their parents’ possible exposure to pesticides have raised questions over how difficult it may be to retroactively link the two. Alexa Elliott spoke with a physician about this complex process. A Catholic social service organization has opened a fund that will accept donations for the three families. The address for the Three Kids Fund is through the Guadalupe Social Services, POBox 5034,Immokalee, FL 34143. (AUDIO)
