Madeline Brogan says she was making appetizers for a New Year's Eve party and, after microwaving the bag of spinach, she found one big chunk and figured it was a stem or something still frozen, so she put it aside in the sink.
To her horror the next day, she said she discovered what really was in the sink.
"I picked it up and started pulling the spinach off it and realized there were two eyeholes, and it was a little skull," she said. "I ate that eye, or someone did."
Publix said it is investigating.
"We did receive communication from the customer through our customer care department, which was shared with our corporate quality assurance team. They are working through the details with the customer and the supplier. We have not received any additional complaints and believe this is an isolated incident," the store said in a statement to MyFox Tampa Bay.
