I purchased one pot of fat-free-natural yoghurt produced by a major dairy company from the Asda supermarket in Cookstown a few days ago. I opened it this lunchtime today (12th June). It had a use before date of the 24th June 2014 (see below).
I noticed the lumps, clumps of curd on the lid immediately. See below.
Looking at the inside of the container the top part of the yoghurt was less viscous than the bottom, syneresis was starting and grains/lumps/nodules were clearly visible.
The grains / nodules can be clearly seen on the spoon images below.
It is always interesting to see how companies respond to problems. No one answered the contact phone number given on the carton. I also completed a web form on the company website and attempted to contact their PR company using the information on their website. The contact information was not correct however I managed to get the correct information from their website. I eventually got a response of sorts from the website form.
This is the second time in a month that I have bought a stirred yoghurt with this fault. The first time was from a local company in Northern Ireland and it was a natural yoghurt made with whole milk.
