1. Sampling of Food and Drugs.
(a) For Chemical analysis
Number procured formally 200

Of the 200 formal samples, 167 were of milk. For the first time
it can be recorded that no sample was found to be adulterated.

*Sausages 1
Bread 1
*Pork Pie 1
Desiccated Coconut 6

* These articles were suspected to have caused food poisoning
but no organisms likely to cause food poisoning were isolated,
a faecal strain of B.Coli was however isolated from the heart. The
rapid onset of symptoms after the sausages suggested that the
poisoning was due to pre-formed toxin. No pathogenic organisms
were found in the pork pie.
