An urgent recall of Sriracha hot sauce has been issued over fears bottles could explode when opened.

The NSW Food Authority warned bottles of the popular chilli should not be opened if it was bloated and instead returned immediately.

Bottles bought from Coles, Woolwoths and IGA, and independent supermarkets, along with Asia food shops, were included in the recall.

The regulator said the defect meant lactic acid built up inside causing certain bottles to 'bloat' and the sauce to continue to ferment.

They could then explode when opened and splatter the hot, bright red chilli all over people and their property.

Recall applies to Sriracha hot chilli sauce 17oz and 28oz, sold in a plastic bottle, with a best before date of March 2021.

The product distributed by Kien Fat Trading was recalled earlier in the month in Europe and the U.S. due to the same problem.

Sriracha, which originates from Thailand, is one of the most popular hot sauces in the world and ubiquitous in pantries and on restaurant tables.
