Danone Yoghurt tastes like chemicals

Ive been buying your brand of yoghurt for years as I havnt completely trusted other brands. I put your yoghurts in my kids lunch boxes. The other day i decided to have a yoghurt which tasted like chemicals! It made me feel so sick and almost burnt my throat. Ive completely lost trust in your brand and I doubt will buy your yoghurts again. Ive kept the opened yoghurt aside if you would like collect it to test it. I bought 2 packs of 8 and I refuse to give it to my kids. The expiry date is 23 October and the code below is 17:51AR1 253.<br>
