Paris leaders look at baby milk. Many countries send milk back. The police start a check. They want to know if people were not careful. This is about milk with bad poison.
Big milk companies are in this. Nestle and Danone are names. Small companies are also checked. Parents say babies are sick. Babies ate milk and then vomited. Many babies in the UK were sick.
The problem is with oil. This oil is in baby milk. It helps babies grow. The bad poison can come from this oil. A company in China made the oil. This company is not making it now.
The poison makes babies sick. Babies can vomit and have a sore tummy. The poison is very strong. So, many milk boxes are taken from shops.
This is a big problem. It makes us think about safe food. We need good rules for babies.
