4. Domestic (August)—4 cases—1 Notified—Chicken.
5. Works Canteen (September)—10 cases—0 Notified—

Apart from these outbreaks the following individual cases were
investigated:—
1. A case was notified in January. The individual thought
that the cause was food taken at a dance in another Borough. Enquiries
in that Borough did not reveal any other case arising after
the dance and further investigations were not thought likely to
serve a useful purpose.
2. A young man reported in March that he had been found to be
a Salmonella carrier some 6 months previously, and had been on that
account dismissed from his post as a Male Nurse in a Hospital.
Examination showed that he was still a carrier. He was treated
with large doses of Sulphaquanidine and although this appeared to
reduce the number of carrier organisms, it did not eliminate them.
He was then admitted to St. Bartholomew's Hospital and there
treated with Streptomycin successfully.
3. A child of 2 was found in May by a Hospital, to have a
Salmonella infection. Intensive investigations were carried out and
it was finally believed that infection had occurred from a sick hen
which was found to be similarly infected. Full details are being
published elsewhere.
4. Two cases were notified in July, but arose as part of a large
outbreak that was fully investigated in another districte.
5. A notification was received in October that a woman had
developed a Salmonella infection and was being treated in Hospital.
