Q1: Texas Sanitarian (RS) licensing authority and statute?
A. Texas Commission on Environmental Quality TCEQ only
B. Texas Department of State Health Services DSHS per Texas Health and Safety Code Chapter 439 - Texas Board of Professional
Sanitarians - requires science degree, experience, exam
C. U.S. Food and Drug Administration FDA only
D. No licensing required in Texas
Answer & ULTRA-Detailed Rationale:
B. Texas Department of State Health Services DSHS per Texas Health and Safety Code Chapter 439 - Texas Board of
Professional Sanitarians - requires science degree, experience, exam
CONCEPT: Who regulates the Registered Sanitarian (RS) credential in Texas and under what law. CORRECT ANSWER - A is
CORRECT: Texas RS is licensed by Texas Department of State Health Services (DSHS) Professional Licensing under Health and
Safety Code Chapter 439. The Texas Board of Professional Sanitarians establishes rules: requires minimum bachelor's degree with 30
semester hours science, experience in sanitation, passing the National Environmental Health Association (NEHA) REHS/RS exam or
Texas exam. Must renew biennially with continuing education. WHY B IS WRONG: TCEQ regulates environmental issues - OSSF (30
TAC 285), water systems, MSW landfills - but does NOT license Sanitarians. Many exam takers confuse TCEQ with DSHS because
both deal with environmental health. TCEQ licenses OSSF designated representatives, not RS. WHY C IS WRONG: FDA is federal
agency that writes FDA Food Code model - Texas adopts with amendments in TFER. FDA does not license state sanitarians. Federal vs
state authority trap. WHY D IS WRONG: Texas requires RS license for many environmental health positions - Title 25 TAC. Practicing
without license is violation. Exam loves to test if you know licensing is required. EXAM TIP: Remember DSHS = people licensing
(Sanitarian, Food Manager), TCEQ = systems licensing (OSSF, water).
Q2: Texas Food Establishment Rules TFER - what model code does it adopt?
A. No food code exists - only local ordinances
B. FDA Food Code 2017/2022 with Texas amendments - 25 TAC Chapter 228
C. Texas completely independent code with no FDA basis
D. USDA Meat and Poultry Inspection Code only
Answer & ULTRA-Detailed Rationale:
B. FDA Food Code 2017/2022 with Texas amendments - 25 TAC Chapter 228
CONCEPT: Legal basis of Texas retail food regulation. CORRECT - A: TFER 25 TAC Chapter 228 adopts FDA Food Code (currently
2017 version, transitioning to 2022) with Texas amendments. This is critical - when Texas amendment conflicts, Texas amendment
controls, but base language is FDA Food Code. Covers time/temperature, employee health, cross-contamination, HACCP. WHY B
WRONG: Texas does NOT have completely independent code - it explicitly adopts FDA Food Code by reference. If you answer
independent, you miss that FDA definitions apply. Exam often quotes FDA Food Code language verbatim. WHY C WRONG: USDA
FSIS regulates meat/poultry slaughter and processing plants, not retail food establishments like restaurants grocery stores. Different
agency, different code. Common distractor. WHY D WRONG: Statewide code exists - TFER - not just local ordinances. Local health
departments enforce TFER. EXAM TIP: Know that TFER = FDA Food Code + Texas amendments. When question says per TFER, think
FDA Food Code definitions.

,Q3: Danger zone and TCS foods - define per TFER?
A. Danger zone 41°F to 135°F - TCS = Time/Temperature Control for Safety foods require time/temperature control to prevent
pathogen growth and toxin formation
B. Danger zone 32°F to 212°F - all foods with water
C. There is no danger zone - temperature does not affect food safety
D. Danger zone 0°F to 32°F - only frozen foods
Answer & ULTRA-Detailed Rationale:
A. Danger zone 41°F to 135°F - TCS = Time/Temperature Control for Safety foods require time/temperature control to prevent
pathogen growth and toxin formation
CONCEPT: Temperature danger zone and what makes a food TCS. CORRECT - A: Danger zone 41°F-135°F per TFER/FDA (note old
FDA was 41-135, some texts still show 41-135, Texas uses 41-135). In this range, pathogens like Salmonella, E. coli, Staphylococcus
aureus grow rapidly doubling every 20 min. TCS foods = foods requiring time/temp control: animal origin (meat, poultry, fish, eggs,
dairy), heat-treated plant (cooked rice, pasta), cut leafy greens, cut tomatoes, cut melons, sprouts, garlic-in-oil mixtures. WHY B
WRONG: 32-212°F is range of liquid water, not danger zone. Too broad. Includes safe hot holding 135°F+ which is safe, and cold
holding 41°F below safe. Exam trap uses water physics to confuse. WHY C WRONG: 0-32°F is freezing range - actually inhibits
bacterial growth (doesn't kill). Not danger zone. Pathogens dormant frozen. WHY D WRONG: Temperature is #1 factor in food safety.
Dismissing danger zone is dangerous and factually wrong. This distractor tests if you understand basic microbiology. EXAM TIP:
Memorize 41-135 and TCS definition. Questions often ask which food is NOT TCS - e.g., whole uncut raw produce is NOT TCS, but cut
is TCS.
Q4: Cold holding and hot holding minimum requirements?
A. Cold holding 32°F exactly, Hot holding 165°F or above
B. Cold holding 41°F or below, Hot holding 135°F or above per TFER 228.75
C. No temperature requirements - time as a public health control can be used for any time without limits
D. Cold holding 50°F or below, Hot holding 120°F or above
Answer & ULTRA-Detailed Rationale:
B. Cold holding 41°F or below, Hot holding 135°F or above per TFER 228.75
CONCEPT: Holding temperatures - critical limits for inspection. CORRECT - A: Cold hold 41°F or below, Hot hold 135°F or above.
Measured with calibrated food thermometer. Must be continuous. If cold hold 42-45°F, you have 2 hours to correct to 41°F or discard.
Hot hold below 135°F is out of compliance - must reheat to 165°F within 2 hours or discard. WHY B WRONG: 50°F cold holding is 9°F
too high - allows Listeria, Salmonella growth. 120°F hot holding is 15°F too low - in danger zone - Clostridium perfringens grows. This
distractor uses temperatures that sound close but are violations. Inspector would mark violation. WHY C WRONG: 32°F is freezing, not
required for cold holding - would freeze lettuce. 165°F is cooking temperature for poultry, not hot holding minimum. Confusing cooking
temps with holding temps is common exam trap. Cooking: poultry 165°F 15 sec, ground meat 155°F, steaks/fish 145°F. WHY D
WRONG: Time as Public Health Control (TPHC) exists but has strict limits: 4 hours if no temp control then discard, or 6 hours if initial
temp 41°F and temp never exceeds 70°F. Must be written procedure. Not unlimited. Cannot say no temp requirements. EXAM TIP:
Know cold 41, hot 135, cooking temps separate, and TPHC 4-hour/6-hour rule.

,Q5: Two-stage cooling - what is FDA/Texas requirement?
A. Cool from 135°F to 41°F within 12 hours
B. Cool from 135°F to 70°F within 2 hours, then from 70°F to 41°F within additional 4 hours - total 6 hours per 228.75
C. Cool from 135°F to 41°F within 2 hours total
D. No cooling requirement - can cool at any rate
Answer & ULTRA-Detailed Rationale:
B. Cool from 135°F to 70°F within 2 hours, then from 70°F to 41°F within additional 4 hours - total 6 hours per 228.75
CONCEPT: Cooling TCS foods safely - most common cause of foodborne outbreak if done wrong. CORRECT - A: Two-stage cooling:
Stage 1: 135°F → 70°F within 2 hours (fast through high danger zone). Stage 2: 70°F → 41°F within 4 hours. Total 6 hours. Why two
stages? 70°F-125°F is fastest pathogen growth (C. perfringens). Must move quickly through that. If fails first stage, must reheat to 165°F
or discard. If fails second stage, corrective action. WHY B WRONG: 135→41 in 2 hours is physically impossible for large batches - even
blast chiller struggles. Code allows 6 hours total, not 2. This distractor tests if you know it's two stages, not one impossible rapid cool.
WHY C WRONG: 12 hours is too long - would allow 6 log growth of Clostridium. Product would be unsafe. Outbreaks often linked to
12-hour cooling. Code prohibits. WHY D WRONG: Cooling requirement exists and is critical - 3rd leading cause of outbreaks per CDC.
Saying no requirement is dangerous. EXAM TIP: Use shallow pans, ice bath, blast chiller, ice paddles, smaller portions to meet cooling.
Inspector will ask how you cool large pot of beans.
Q6: Cross-contamination prevention - raw animal foods storage order in cooler?
A. No separation needed if all foods are within date
B. Top to bottom by minimum internal cooking temperature: Ready-to-eat foods top shelf, then seafood/fish 145°F, then beef/pork
steaks 145°F, then ground meats 155°F, then poultry 165°F bottom
C. Only cooking temperature matters - storage order irrelevant
D. Poultry on top shelf above ready-to-eat foods
Answer & ULTRA-Detailed Rationale:
B. Top to bottom by minimum internal cooking temperature: Ready-to-eat foods top shelf, then seafood/fish 145°F, then
beef/pork steaks 145°F, then ground meats 155°F, then poultry 165°F bottom
CONCEPT: Preventing cross-contamination via storage hierarchy - physics of drip. CORRECT - A: Store by ascending cooking
temperature = descending from top: RTE (no cook) top → fish 145°F → beef/pork steaks/roasts 145°F → ground meat 155°F →
poultry 165°F bottom. Reason: raw chicken juices dripping onto RTE salad = Salmonella cross-contamination. Poultry has highest
required cook temp (165°F) to kill Salmonella, so it goes lowest. RTE has no cook step, so must be protected on top. Also separate raw
from RTE, use color-coded cutting boards red meat, blue fish, yellow poultry. WHY B WRONG: Poultry on top above RTE is WORST
violation - raw chicken drips contaminate RTE foods that will not be cooked. This is critical violation on inspection, immediate correction.
Exam often shows diagram of cooler with poultry above salad - you must identify as violation. WHY C WRONG: Date marking does not
prevent cross-contamination. Even within date, raw chicken can cross-contaminate. Separation always required regardless of date.
WHY D WRONG: Storage order IS relevant because of drip physics - cooking temp alone doesn't prevent contamination during storage.
Both cooking temp AND storage order matter. EXAM TIP: Remember mnemonic: RTE, Fish, Beef/Pork, Ground, Poultry = Really Fancy
Burgers Get Prepared. Top to bottom.
