WebThe degradation of chloramphenicol in manure has not been studied systematically. Since the molecule has a number of functional groups (e.g. the aromatic nitro group, the dichloro-acetyl side-chain) that could be attacked by known biotic processes, the behaviour of the compound cannot be predicted. The most serious side effect of chloramphenicol treatment is aplastic anaemia. This effect is rare but sometimes fatal. The risk of AA is high enough that alternatives should be strongly considered. Treatments are available but expensive. No way exists to predict who may or may not suffer this side effect. The effect usually occurs weeks or months after treatment has been stopped, and a genetic predisposition may be involved. It is not known whether monitoring the bl…
