POLIOMYELITIS AND ACUTE ENCEPHALITIS.
During the course of the year three cases of poliomyelitis
occurred in the Borough. Of these, 2 were boys aged 8 and 15
years, and 1 female aged 42 years.
Unfortunately 1 case, the boy aged 15 years, proved rapidly
fatal. One of the cases was non-paralytic and a follow-up of the
remaining case shows good recovery.
FOOD POISONING
Of the 15 cases of food poisoning which were notified during
the year, 13 were single cases, 7 being due to Salmonella Organisms
and in 6 cases no causative organism was identified.
The remaining two notified cases, together with 2 further
cases ascertained during enquiry, constituted a small outbreak of
food poisoning due to staphyloccus pyogenes. Two households
consisting of 2 persons each were involved, the housewife in each
case purchasing pressed brisket beef from an Enfield grocer and
becoming ill a few hours after eating some of the meat on the same
day. The other member of each family took the remainder of the
meat to work in a sandwich lunch on the following day and became
similarly ill a few hours later. The severity of the illness necessitated
admission to hospital in three cases.
The suspected food, pressed brisket beef, was manufactured
by a firm in another Borough, and sold by a grocer in Enfield.
During the inspection of the grocer's shop it was observed that an
assistant, whose duties consisted mainly of slicing cooked meats,
had a number of partially healed cuts on his hands. Samples of
faeces from one of the patients, and samples of brisket and silverside,
contained staphyloccus pyogenes, phage type similar to the
type found in swabs taken from the Assistant's fingers.
