A mother claimed Tuesday her 10-month-old was hospitalized after eating cannabis left in the baby changing room of Starbucks coffee shop in Essex, England.

Vicky Albert, 27, said she entered the coffee shop for a drink while she was shopping with her husband and her daughter, Amiyah. She took the daughter to the baby changing room to change her nappy. She saw her baby swallowing something and when she lifted the changing mat, she saw "loads of little bits of weed" on the table. The baby was taken to a nearby hospital where she spent over six hours.

"I went into the changing facilities which was just a disabled toilet with a baby change table. I put down my changing mat and as I supported Amiyah, I lent over to get the baby wipes and a nappy. As soon as I get grabbed them I saw her chomping on something. There was something green in her mouth and as I prised her mouth open, she swallowed it. I then lifted up the changing mat and noticed loads of little bits of weed and tobacco on the table,” the mother said, Mirror reported.

"I panicked and screamed out for my husband and said 'is that what I think it is? My husband called 111 and I went to speak to the staff at the counter who were so rude, they didn't even apologize and just rushed in there to clean it up and another staff member said 'she should watch where she puts her baby'. A customer in the queue even heard it and was outraged and left saying she would never be coming back,” she added.

The baby was taken to a hospital after she started throwing up.

"Her belly is a bit irritated and we are keeping an eye on her. We think she will be fine but I cannot believe how we were treated. My husband said it should be logged and they told us they couldn't access the system and said 'if you are so concerned then why are you still here - if that was my kids I would be straight down to hospital',” Albert said.

When Albert questioned when the changing room was last cleaned and checked, a staff member replied, “I checked them when I came in which is what I always do. Since then, the queue has been out the door. We just haven't stopped. It's just human error."

Starbucks is investigating the incident.

“We are very sorry to hear of this customers’ experience in our store and have been in touch with them directly today to apologize and understand what happened whilst we carry out our own investigation. We aim to make our stores a welcoming environment so when our standards have not been met, we act as quickly as we can to make it right,” a Starbucks spokeswoman said.
