gravity, storage might well be in a compartment in the stem where the refuse could be fed through
a self-closing hopper on deck and released through the shell plate and so dispersed in the wake
of the ship. Constructional detail could facilitate proper cleansing and other treatment as necessary.
SECTION XIV
PUBLIC HEALTH (SHELLFISH) REGULATIONS, 1934
The Public Health (Shellfish) Regulations, 1934, confer powers on a local authority whereby
on receipt of a report of their Medical Officer of Health that the consumption of shellfish taken
from a laying is likely to cause danger to public health, they may make an Order prohibiting the
distribution for sale for human consumption of shellfish taken from the laying either absolutely or
subject to such exceptions and conditions as they think proper, having regard to the interests of
the public health.
Two such Orders have been made. The first in 1936, covering the public and private layings
bordering that part of the foreshore of the Estuary of the River Thames between Canvey Island
and Shoeburyness; and the second, in 1957, covering the foreshore or waters bordering on that
part of the Estuary of the River Thames or any tributary thereof, between Garrison Point, Sheerness,
and Warden Point in the Isle of Sheppey.
No contraventions of the Orders were reported during the year.
Oyster Industry
Fattening of imported Portuguese oysters in the River Roach, as reported in the last two
Annual Reports, was discontinued from December, 1965, but the cultivation of native oysters
continues satisfactorily. Layings are visited from time to time.
Cockle Industry
The cockle industry at Leigh continues to flourish and nothing of special significance has
happened during the year. The eight approved establishments for sterilizing cockles all conform
to a high standard of hygiene and the several requirements of the Order made by this Authority
for the purpose of the Public Health (Shellfish) Regulations. Inspections are normally carried out
whilst the establishment is working and the general condition of the process has been found to be
satisfactory. No illness has been reported during the year which could be attributed to the consumption
of cockles from these establishments.
