Original questions written to this exam's published syllabus and pattern. Not past papers.
1. A 1 mL portion of a 10^-3 dilution of raw milk is pour-plated and gives 156 colonies. What is the plate count of the milk?
C. 156,000 CFU/mL
Count = colonies x reciprocal of dilution / volume plated = 156 x 1,000 / 1 = 156,000 CFU/mL. Multiplying by 100 (15,600) or 10,000 (1,560,000) is a dilution slip; 156 ignores the dilution altogether.

2. A disease that is present in a cattle population at a usual, fairly constant and predictable frequency is described as:
A. Enzootic
Enzootic (the animal equivalent of endemic) means present at the expected, stable level. Epizootic means clearly above the expected level; sporadic means irregular and unpredictable; exotic means not normally present in the country.

3. Which organism is the preferred indicator of recent faecal contamination of drinking water?
B. Escherichia coli
E. coli lives in the gut of warm-blooded animals and does not usually multiply in water, so its presence signals recent faecal contamination. Heterotrophic counts describe general bacterial load and biofilm, not faecal origin; Pseudomonas and Staphylococcus are not faecal indicators.

4. Compared with older 'one medicine' thinking, what does the 2021 OHHLEP definition of One Health explicitly add?
D. Plants and the wider environment, including ecosystems, as linked parts of health
The OHHLEP definition names humans, domestic and wild animals, plants and the wider environment including ecosystems. It describes an approach, not a treaty, gives no sector leadership by right, and is deliberately broader than livestock-human disease.

5. Using a model daily diet of 300 g muscle, 100 g liver, 50 g kidney, 50 g fat and 1.5 kg milk, residues are 50, 200, 400, 100 and 20 µg/kg in those foods. The ADI is 2 µg/kg bw per day for a 60 kg person. What share of the ADI does the diet supply?
C. 75%
Intake = 0.3x50 + 0.1x200 + 0.05x400 + 0.05x100 + 1.5x20 = 15 + 20 + 20 + 5 + 30 = 90 µg. Limit = 2 x 60 = 120 µg. 90/120 = 75%. Adding the concentrations without weighting by intake gives 642%; leaving out milk gives 50%; dividing by the ADI without body weight gives 45.
