ICAR AICE-JRF/SRF Food Risk Analysis: Risk Assessment, Management & Communication: practice questions

1 · The Codex risk-analysis framework · medium

Why does Codex call for functional separation between risk assessment and risk management?

1. Because assessment must be done only by industry
2. So that management decisions can ignore the assessment
3. To prevent assessors and managers from ever communicating
4. To protect scientific integrity and clarify roles

2 · Dose-response models · hard

Using the exponential dose-response model P = 1 − exp(−r d), with r = 0.001 and a dose of 100 organisms, what is the probability of illness?

1. 0.095
2. 0.905
3. 0.001
4. 0.100

3 · Exposure assessment and dietary intake estimation · hard

Why do food balance sheets tend to overestimate dietary exposure?

1. They exclude staple foods from the calculation
2. They record only foods eaten by children
3. They use consumers-only data for every food
4. They measure food available, not eaten

4 · Exposure assessment and dietary intake estimation · hard

Aggregate exposure differs from cumulative exposure in that aggregate exposure combines:

1. Only dietary routes; cumulative includes occupational routes only
2. Exposure of adults; cumulative refers only to children
3. Several substances for one route; cumulative combines several routes for one substance
4. Many routes for one substance versus many substances with one mode of action

5 · Quantitative microbial risk assessment · medium

Which JEMRA assessment found that most listeriosis risk comes from foods that support growth and are eaten after long storage?

1. Salmonella in eggs and broiler chickens
2. Listeria monocytogenes in ready-to-eat foods
3. Vibrio species in seafood
4. Campylobacter in broiler chickens

6 · Quantitative microbial risk assessment · medium

Monte Carlo simulation in QMRA is used to:

1. Assign legal responsibility for an outbreak
2. Replace dose-response models entirely
3. Count colonies on agar plates automatically
4. Propagate input distributions to outputs

7 · Chemical risk assessment and margin of exposure · hard

A genotoxic carcinogen has a BMDL10 of 0.4 mg/kg bw/day and exposure is 0.002 mg/kg bw/day. What is the margin of exposure?

1. 0.005
2. 20
3. 200
4. 2,000

8 · Food safety objectives, performance objectives and performance criteria · easy

The appropriate level of protection (ALOP) is often expressed as:

1. Log reductions per minute of heating
2. Cases of illness per 100,000 people per year
3. Milligrams per kilogram of body weight
4. Colony-forming units per gram of food

9 · Risk ranking and risk profiles · medium

According to the WHO FERG estimates published in 2015, roughly how many food-borne illnesses occurred worldwide in 2010?

1. 6 billion
2. 6 million
3. 600 million
4. 60 million

10 · Risk management options · medium

Which closes the risk management loop by showing whether measures are working?

1. Monitoring and review, including surveillance of illness and hazards
2. Publishing the risk profile on the agency's website
3. Choosing the dose-response model
4. Setting risk assessment policy
