Supermarket giant Sainsbury's has issued an apology over its substandard hygiene at the Stevenage Poplars store - just days after admitting not meeting hygiene standards at its Corey's Mill store.

A worried customer had contacted the Comet to raise concerns of salmonella over dirty shelves holding raw chicken at the Stevenage Corey's Mill supermarket.

Sainsbury's said its stores have "strict hygiene rules" and apologised that "these usual high standards were not met in this instance".

Now, another customer has come forward to highlight the dirty state of the shelves holding raw chicken and milk at the Stevenage Poplars store.
