   • D-15 °C
   Ver respuesta

   Respuesta: D. -15 °C

   The limit is -18 °C with brief upward fluctuations of no more than 3 °C during transport, so -18 + 3 = -15 °C.

4. Pregunta 4 de 16

   What does EU law say about cooling food that will be kept or served chilled after cooking?

   • AIt must be cooled slowly to keep the flavour
   • BIt must be cooled as quickly as possible
   • CIt must be frozen within 10 minutes
   • DIt must be left at room temperature overnight
   Ver respuesta

   Respuesta: B. It must be cooled as quickly as possible

   Annex II, Chapter IX of Regulation 852/2004 says such food must be cooled as quickly as possible after heat processing to a temperature that does not risk health.

5. Pregunta 5 de 16

   Why can recommended fridge, cooking and hot-holding temperatures differ between EU countries?

   • AThe EU has banned all national food safety rules and guidance
   • BGeneral EU hygiene rules mostly leave the numbers to each country
   • CThermometers in each EU country use a different temperature scale
   • DFood behaves differently in each country because of the weather
   Ver respuesta

   Respuesta: B. General EU hygiene rules mostly leave the numbers to each country

   Regulation 852/2004 requires safe temperatures but leaves most values to national rules, guidance and sector guides, so values can differ.

   FSAI advises keeping hot food above 63 °C.

9. Pregunta 9 de 16

   Under FSAI guidance from Ireland, food not kept above 63 °C should be used within 2 hours of cooking. A stew finished cooking at 11:15 and is kept below 63 °C. By when should it be used?

   • A15:15
   • B13:15
   • C12:15
   • D13:45

    Mon	4
    Tue	3
    Wed	7
    Thu	5
