The company, which supplies chocolate to food groups such as Unilever for its Magnum ice creams and Nestle for its KitKat bars, said operating profit fell 2.3% to 553.5 million Swiss francs ($557.6 million), missing analyst forecasts for 586.5 million francs.
The figure was hit by the one-off impact of 76.9 million francs related to the salmonella outbreak at the Wieze factory in Belgium detected in June.
Sales volumes were also affected by the shutdown, with full-year volumes increasing to 2.3 million tonnes. The 5.3% increase represented a slowdown from the 7.9% increase during the first nine months of the year.
Despite the disruption, Barry Callebaut achieved its guidance of increasing volume growth of 5% to 7%. But it missed its goal of raising its operating profit in local currencies at a higher level than volumes.
Operating profit in local currencies, which cuts out the impact of currency swings, increased by only 0.1% during the year.
Barry Callebaut had been due to release its earnings on Wednesday, but published the figures early due to an "unforeseen event".
