«How can the town authorities police the sale of foodstuffs? It is very difficult. When a wild pig is seen dead in a street, and then suddenly disappears, people do not know whether it has been cleared up or cooked. Often they are right to suspect it has been disposed of in their take-away pies. London records are full of cases where a dead pig has been decomposing in the town ditch for a week or so and then ends up being scavenged by a pie-maker. Sometimes medieval people take recycling too far.»
