The use of antibiotics by farmers to boost growth in their stocks
(by preventing infections in order to maintain healthy appetites
and muscle fibre) appears to have led to increased antibiotic
resistance in humans. The European Union is sufficiently alarmed
to have banned the use of five common animal antibiotics. Instead
of encouraging farmers to return to healthier ways of stock-rearing
(larger, airier enclosures, more nutritious feeds, etc.) scientists
are developing an alternative chemical fix - poultry antibodies
which block the actions of appetite-suppressing neurotransmitter
peptides, and a feed additive called conjugated linoleic acid
(CLA), which blocks the chemical messengers which cause muscle-wasting.
DCV, the manufacturers of CLA, will be conducting European field
trials in early 2000.
Ed.- Does this not infer that we will soon be offered chickens
whose illnesses are masked by artificially good appetites and
artificially blossoming flesh?
