ne dépasse pas le 5°C avec un marge de tolérance de 1°C  

Cooling reduces the proliferation of bacteria, bacteria exist naturally all around us are found in soil, air and water and in the food we eat, and when assistance for growth, such as: food, moisture factors available and temperatures appropriate, they grow and multiply rapidly and some have a growth rate of up to degree certain lead to infection. And temperatures ranging from the growth of bacteria that grow in between 40 - 140 ° F (5 - 60 ° m) This is called the long and hazardous area where bacteria multiply some numbers every twenty minutes. Therefore, you must adjust the refrigerator temperature at a temperature of 40 ° F (5 ° m) to inhibit the growth of bacteria and to protect perishable foods.

5 to 63 degree that is the dangerous zone. For hot food it suppose to be 63 degree or above, and for cold food its 5 degree or below

The standard states 5 degrees Celcius

for to keep the food safe must be 1 to 5

Right temperature is below 40 °F

Answer based on middle east, 1°C to 4°C. But it veries product to product for the better storage. E.g., Meat storage for shortime in chiller must be 1°C where normal fruits and vegetables can be stored upto 7°C.

the Cold food temperature is 1◦C to 4◦C

the righ temprature of cold food is 2 - 8 degree centigrade.
