Hens can begin producing Salmonella enteritidis infected eggs within ______ days post infection.

Explanation:
The timing hinges on how Salmonella enteritidis can reach and contaminate the hen’s reproductive tract. After a hen is infected, the bacteria must travel to the ovaries and oviduct and become incorporated into forming eggs. That process takes time, so contaminated eggs don’t appear immediately. In hens, this typically begins about three weeks after infection, meaning eggs produced within roughly twenty-one days can be infected even if the bird shows no illness. This is why the correct window is about twenty-one days.
