As well as the relatively large number of cases of typhoid fever resulting from the Zermatt outbreak, the last few months have seen several outbreaks of both typhoid and paratyphoid in different parts of the country, all having food as the suspected or proven vehicle, except perhaps for the most recent South Shields out‐break, where as yet the source has not been traced, although canned meat is suspected. In small outbreaks it is rarely easy to quickly pin‐point the food vehicle; usually none of the infected food remains; it takes time to confirm clinical diagnoses by bacteriological exam‐ination of sera, faeces, etc., and frequently a food is implicated only by suspicion, although usually based upon good circumstantial evidence.
