Introduction
The Oregon Sanitarian Exam assesses the knowledge, skills, and professional
judgment required of environmental health specialists practicing in Oregon. This
examination evaluates competency across foundational theory, applied professional
knowledge, and regulatory compliance. Questions are presented in multiple-choice
and scenario-based formats to simulate real-world decision-making. Candidates
must demonstrate understanding of food protection, water and wastewater systems,
waste management, vector control, and the legal frameworks governing
environmental health practice. The exam emphasizes practical application and
critical thinking, ensuring that registered sanitarians are prepared to protect public
health and the environment in diverse professional settings.
SECTION ONE: QUESTIONS 1–50
,1. An environmental health specialist is investigating a suspected foodborne
illness outbreak linked to a local restaurant. Multiple patrons report
gastrointestinal symptoms within 24 hours of eating at the establishment.
Which of the following is the most appropriate FIRST action?
A. Immediately close the restaurant pending laboratory confirmation
B. Interview the restaurant manager about food handling procedures
C. Collect food samples from the restaurant's walk-in cooler
D. Notify the Oregon Health Authority of the suspected outbreak
🟢 Correct Answer: D. Notify the Oregon Health Authority of the suspected
outbreak
🔴 Rationale: Oregon administrative rules require prompt notification of
suspected foodborne illness outbreaks to the state health authority. Notification
enables coordinated investigation and response. While interviewing the manager
and collecting samples are appropriate investigative steps, notification to OHA
should occur first to ensure proper epidemiological tracking and resource
coordination.
2. Under Oregon Administrative Rules, a food establishment regulated by the
Oregon Health Authority includes which of the following?
A. A produce stand offering fresh fruits and vegetables
B. A grocery store with a deli counter
C. A bed and breakfast facility
D. A food processing plant
🟢 Correct Answer: C. A bed and breakfast facility
🔴 Rationale: OAR 333-150 defines food establishments regulated by OHA to
include bed and breakfast facilities. Produce stands, grocery stores, and food
processing plants are regulated by the Oregon Department of Agriculture under a
separate regulatory framework.
,3. A sanitarian inspects a restaurant and finds that raw chicken is stored above
ready-to-eat salad in the walk-in cooler. What is the primary public health
concern with this practice?
A. Temperature abuse of the chicken
B. Cross-contamination from drip of raw juices
C. Inadequate cooling of the salad
D. Pest attraction to raw poultry
🟢 Correct Answer: B. Cross-contamination from drip of raw juices
🔴 Rationale: Storing raw animal foods above ready-to-eat foods creates a risk
that juices containing pathogens like Salmonella will drip onto and contaminate
the ready-to-eat food, which will not receive a subsequent cooking step. Proper
storage order places raw foods below ready-to-eat items.
4. What is the minimum internal cooking temperature for ground beef in a
Oregon food establishment?
A. 135°F
B. 145°F
C. 155°F
D. 165°F
🟢 Correct Answer: C. 155°F
🔴 Rationale: The Oregon Food Sanitation Rules adopt the FDA Food Code, which
requires ground beef and other ground meats to be cooked to a minimum
internal temperature of 155°F for 17 seconds. This higher temperature is necessary
because grinding distributes surface bacteria throughout the product.
5. A sanitarian is conducting a plan review for a new restaurant. The owner
proposes installing a handwashing sink in the food preparation area. What is
the minimum requirement for handwashing sink location?
, A. One sink within 50 feet of any food preparation area
B. A sink in each food preparation, food dispensing, and warewashing area
C. A single sink in the employee restroom is sufficient
D. Handwashing sinks are required only in the warewashing area
🟢 Correct Answer: B. A sink in each food preparation, food dispensing, and
warewashing area
🔴 Rationale: The Food Code requires that handwashing sinks be conveniently
located and accessible in all food preparation, food dispensing, and warewashing
areas. This ensures employees can wash hands frequently without leaving their
work area, reducing contamination risk.
6. Which of the following is considered a potentially hazardous food
(time/temperature control for safety food) under Oregon food rules?
A. Whole wheat flour
B. Sliced cantaloupe
C. Vinegar
D. Dry pasta
🟢 Correct Answer: B. Sliced cantaloupe
🔴 Rationale: Cut melons are classified as potentially hazardous because the
interior flesh supports bacterial growth once the protective rind is breached. Flour,
vinegar, and dry pasta are shelf-stable and do not require time/temperature
control for safety.
7. A sanitarian observes a food employee wiping a cutting board with a soiled
cloth and then continuing to prepare food. What is the correct immediate
corrective action?
A. Instruct the employee to use a different cutting board
B. Discard the cloth and require proper cleaning and sanitizing of the cutting
board
