SCA Hygiene is recalling a line of nappy pants after an "unusual odour" was discovered in one batch of the products when individual packs or cartons were opened.
The Treasures Nappy Pants - Toddler and Walker range with date codes of September 19, September 2 or October 8 last year have been voluntarily recalled.
Tests have indicated a "very low risk of any potential adverse health effects" and the company is completing comprehensive investigations.
It said it believed the incident is isolated to "a handful of packs" but the company is recalling the entire batch as a precautionary measure.
Company president Peter Diplaris said it was not a manufacturing issue.
