The unsatisfactory Chinese egg was disposed of as follows:
T C Q L
Returned to China 10 8 0 0
Re-pasteurised 18 18 0 0
In addition 874 control samples were taken from the two pasteurisation plants
in the Borough as follows:
British egg 309
Chinese egg 60
South African egg 505
874
All these samples were found to be satisfactory.
The large number of South African control samples is accounted for by the
fact that some 300 tons of unpasteurised egg arrived in the Borough during 1966/67
and had to be pasteurised before distribution.
The following types of Salmonellae were isolated during routine sampling of egg products during 1967:
| Country of Origin | Organism | No. of samples |
|---|---|---|
| Denmark | Salmonella Oranienburg | 1 |
| U.S.A. | Salmonella Montivideo | 2 |
| Salmonella Tennesee | 1 | |
| Salmonella Worthington | 1 | |
| 5 |
