AN outbreak of hepatitis A linked to packets of Nanna's frozen mixed berries is expected to wipe nine per cent off Patties Foods' net profit this year. Patties began recalling its Nanna's and Creative Gourmet berries earlier this year after 18 people were infected by the hepatitis A outbreak. The company said it expects its 2015 net profit to be $15 million, about $1.5 million lower than previously targeted. This compares with $16.7 million for 2014. Managing director and chief executive Steven Chaur said: "We have been significantly impacted in FY15 … as a result of the frozen berries recall event". Mr Chaur said the company's global testing had continued to find no trace of hepatitis or E.coli contamination. "Patties continues its 'positive release' protocol on all its frozen berry products, which means every batch is now tested in Australia for HAV and E.coli, and are only released to market when negative test results are provided," he said. "All Nanna's and Creative Gourmet berries now being released to supermarkets have passed this test with nil detection. Nanna's and Creative Gourmet berries are amongst the most rigorously microbiologically tested berries now sold in the Australian market." Mr Chaur? said the performance of the company's core savoury and sweet pastry brands, which include Four'n Twenty, remain "solid, despite significantly increasing meat prices". According to Mr Chaur the board was yet to decide on a final dividend, after it deferred its interim payout in February. "The Board's decision, together with a possible final dividend, will be further considered by the Board when it reviews the financial statements for FY15," he said. Patties is expected to announce its full year earnings on August 24. Shares in the $170 million company fell less than one per cent to $1.21 after the announcement.
