The committee of inquiry into the outbreak of food poisoning at Stanley Royd Hospital identified serious deficiencies in the management of the outbreak and urged all health authorities to learn from the incident and prepare adequate plans for dealing with any future outbreaks. A survey of district health authorities in England showed that most authorities do not yet have a written plan or that their plans are incomplete and inadequate. The appreciable resistance to such planning suggests that most health authorities would be unable to deal with outbreaks of food poisoning effectively and efficiently.
