Easter egg dyes can be unsafe, the National Consumer Protection Center warns. Buyers should get suspicious if the label indicates a great number of E codes or if the composition is not indicated at all.
According to the Center, most coloring agents on the market can be toxic, simply because they are industrially manufactured from artificial dyes. Buyers should avoid those dyes which contain E numbers that are hard to pronounce and which can be ingested by permeating the egg shell. These include azorubine E122, tartrazine E102, brilliant blue FCF E133, Xanthan gum E415 etc.
Also, people should avoid keeping boiled for longer than 5-7 days, even if they are kept in the fridge. Moreover, children and pregnant women or nursing mothers should consume boiled eggs that are no older than 2-3 days.
