The blue stains found by customers on some vegetables purchased from NTUC FairPrice are "residual remnants of undissolved fungicide", a spokesperson for the supermarket chain said.
AVA said that the stains could be due to the use of a copper-based fungicide, approved to be used in agriculture and easily removed by washing.
FairPrice said on Thursday it has made its concerns known to the supplier of the vegetables and has "taken the necessary actions to ensure this does not recur".
Customers who bought fresh produce from FairPrice and find the quality to be unsatisfactory can return the product to the same store with their receipt before the stated expiry date for a full refund or exchange, it said.
