Yes, I am talking about business men who are in food business. Especially who are in production level. To avoid poisoned mango we started collecting mango from Rajshahi (famous for mango production in Bangladesh). But now a day people use to spray chemicals when the mangoes were in the tree. So, there is no way to avoid these poisons.
Few days ago a school teacher brought some food trees at home. Some small mango and lemon were in the tree when she brought those. After 3 months she found fruits are still in same small size and hard. It’s not growing or getting rotten. Like a plastic one. But they were real. Don’t know what they did to them.
