The study found that 94% of fruit spread samples tested did not contain undeclared sulphites.
About three samples (i.e. 6%) contained sulphites. One product was determined to pose a health risk and was immediately recalled. The sulphite levels in the other two products were considered to be safe for human consumption.
Sulphites are often added to foods as a preservative to prevent spoilage and/or to maintain colour. They could also be present due to cross contamination during food production.
While not a health concern for most consumers, sulphites can cause a serious reaction in consumers with a sulphite sensitivity.
