essentialsaltes...investigating 'macroscopic' food safety testing, i.e. the analyst looks at the food and decides whether it suffers from some defect or other. The whole process is described in bland scientific terms so our minds do not correlate their contents:
"Place 1 lb of lingonberries or sauce in a suitable deep container (No. 10 can or equivalent). Fill with water to within about 1 in. from the top. Thaw the berries if frozen. Stir several times and pick out the larvae which float to the surface."
For everyone's comfort, I have deleted a few other extracts I found. But not this one:
"Spiny-headed worms (Acanthocephala). These worms live in the intestine and are attached to the wall by a protrusible proboscis covered with recurved hooks; the worms vary in length from less than an inch to more than a foot. The body of individuals from most species is elongate, flattened and capable of extension. No digestive tract is present at any stage of their life cycle; food is absorbed directly from the host's intestine.
...
If the average number of parasites found in the 3 subsamples is less than 2 per kg, the lot is considered passable."
