2004, as reported by just-food.com: The European
Food Safety Authority (EFSA) has okayed the use of the
generally toxic chemical formaldehyde in chicken feed.
EFSA’s Scientific Panel on Additives and Products
or Substances used in Animal Feed (FEEDAP) concluded
that the chemical used as a fattener can be safely fed
to chickens as long as dosage limits are respected.
The panel saw no ill effects to the chickens when dosages
did not exceed 660 mg per kg of feed but noted that
there “was little margin for error (over dosage)
before adverse effects were apparent”.
Formaldehyde is already authorised in the European
Union (EU) for use in skimmed milk for piglets up to
the age of six months and within silage for all livestock.
