The Cooked Meats were, as reported upon last year, frequently
found to have heavy counts and emphasises the importance of reducing
handling to a minimum and for a strict supervision and frequent check
of the premises.
The sausage samples represented 17 brands and consisted of 24 pork,
5 beef and 5 mixed meats. Twenty-seven of the samples were from local
cafes and seven from a local manufacturer. Twenty-three samples were
raw, two samples were cooked and nine samples were divided into two,
half the sample being raw and the remainder cooked. Twenty-six samples
were without protective covering and eight were in their original pack.
The cooked samples had either been boiled for 5 minutes or grilled for
approximately & - 34 of an hour.
RESULTS
Total Count
The number of viable organisms in the raw samples varied from 70,00060,000,000/gm.
7 pre-packed samples had a count between 70,000 - 1,200,000/gm.
1 pre-packed sample had a count of 9,800,000/gm.
11 unpacked samples had a count between 400,000 - 10,000,000/gm.

THE TOTAL COUNT IN COOKED SAMPLES VARIED FROM 1,000 - 100,000/gm-
One sample contained 5,200,000 viable organisms per gm. This high total
count was found to be due to heat resistant aerobic spore bearers.
