Which of the following foods requires the least caution in handling?

Bottles of mustard require the least caution in handling primarily because they are shelf-stable condiments with a high acidity level, which inhibits the growth of harmful bacteria. Unlike perishable foods such as meat, poultry, cut fruits, or fresh eggs, condiments like mustard can be stored safely at room temperature for extended periods without the same risk of foodborne illness. This makes them far less susceptible to spoilage and cross-contamination when compared to items that require more stringent handling and storage practices to ensure food safety.

In contrast, meat and poultry are prone to bacterial growth if not stored or cooked properly, while cut fruits can be at risk for contamination once they are exposed to the environment. Fresh eggs and egg products also need careful handling to prevent salmonella and other bacterial infections. Therefore, mustard does not present the same level of risk, allowing for more leniency in its handling and storage.
