Walmart Lucknow (Fresco Egg) - Fake eggs or artifical eggs

I had bought * crate of Fresco Eggs from Walmart Lucknow on **/**/****. But these were found to be fake eggs or artificial eggs. My family member had sever stomach pain after eating these eggs. On checking these eggs were found to be fake or artificial. It is shocking that food items bought from Walmart are fake. We have always trusted Walmart that is why we buy from Walmart but now I am shocked that a compancy like walmart also does not have proper quality checks which can have serious health impact on consumers. Selling fake food items is a serious offence and stern action must be taken aganist the company and the supplier. I seek action agnist supplier of Fresco Eggs and Walmart Lycknow for selling fake eggs.
