Which of the following infractions falls under Category 2?

Category 2 infractions typically pertain to violations that can significantly affect the safety and quality of commodities. This category often includes serious hygiene issues that could lead to health risks or product contamination.

Fecal dirts and leakers fall within this realm because they represent direct risks to food safety. Fecal contamination can introduce harmful pathogens, making the product unsafe for consumption. Similarly, leakers indicate that the integrity of packaging has been compromised, which can lead to the exposure of contents to contaminants and further health risks. Therefore, these infractions warrant a higher level of scrutiny and prompt corrective action to ensure consumer safety.

On the other hand, the other options, while they may involve issues that need addressing, do not carry the same immediate public health implications as fecal dirts and leakers. Refrigeration issues, for instance, relate to temperature control but don't necessarily indicate contamination. Checks and non-fecal dirts and bloody whites and moldy items might signal quality concerns, but they are often classified differently based on the potential health impact they pose.
