Final answer:
Eggs from a grading station can be received at a temperature of up to 7°C to ensure food safety and prevent bacterial growth.
Step-by-step explanation:
If eggs come from a grading station, they can be received at a maximum temperature of 7°C. It's important to handle eggs at the correct temperature to prevent the growth of bacteria and ensure food safety. The other options given, including 13°C, 4°C, and 0°C, are not the correct temperatures for receiving eggs from a grading station. According to food safety standards, keeping eggs at 7°C or lower is necessary to minimize the risk of bacterial contamination, such as from Salmonella.
