What is the shelf life of the bowtie feta pasta salad?

The shelf life of bowtie feta pasta salad being 3 days is based on food safety standards and best practices for storing prepared food items. Salads containing pasta, cheese, and perishable ingredients like vegetables are prone to bacterial growth once they are prepared and exposed to air. Ideally, for optimal freshness and safety, such salads should be consumed within a few days of being made.

In this case, 3 days allows for maintaining a balance between enjoying the salad at its peak flavor and ensuring it does not present health risks. After this time, the quality tends to decrease, and the likelihood of spoilage increases, making it less safe to consume. Storing it in proper conditions, such as refrigeration, can help extend its safety slightly but generally, 3 days is considered a prudent timeframe for prepared salads like this one.

The other options suggest either a shorter or longer shelf life, which would not align with established guidelines for prepared salads, thus potentially compromising food safety and quality.
