Example question 186 · Cooking

“Microwaving food kills bacteria regardless of internal temperature.”

Example question 188 · Cooking

“Cooking food thoroughly can’t always make it safe if toxins have formed.”

True or false?
Reveal the answer

TRUE Some bacteria produce heat‑stable toxins; once formed, cooking won’t destroy those toxins. :contentReference[oaicite:14]{index=14}

Fun fact: This is a key reason rapid chilling and proper storage are essential. :contentReference[oaicite:15]{index=15}

Example question 190 · Cooking

“Cross‑contamination is prevented by using separate cutting boards for raw and cooked foods.”

True or false?
Reveal the answer

Example question 191 · Cooking

“Leftovers safe to eat if they smell fine, regardless of time stored.”

True or false?
Reveal the answer

Example question 193 · Cooking

“Raw sprouts often carry foodborne pathogens and are risky for vulnerable groups.”

True or false?
Reveal the answer
