The unsettled stomach of a 120-kilogram pig was to blame for a fumy false alarm near Bendigo on Tuesday night.

Fifteen firefighters and two tankers rushed to respond to a report of a strong smell of gas after their pagers sent an alert about 10.30pm.

The area has been identified as one of the state's most at-risk of bushfires and residents are able to use only bottled gas, thus increasing the risk of a blaze.

But when the crews arrived at the house in Axedale 10 minutes later, the source of the offending smell was clear.
