？
Is this bread still within its expiration date?
Literal
This bread [topic-って] best-before-date okay [question-か]?
って is the casual topic marker (colloquial というのは). 賞味期限 ('best-before date') is the standard term on Japanese food packaging — distinct from 消費期限 ('use-by date'), which is stricter. 大丈夫か is the blunt masculine question form without です. A very natural, everyday kitchen utterance.
