An unlicensed food delivery service in the Sacramento area has been fined more than $100,000 after several customers were sickened.

The owner of Anna’s Kitchen “repeatedly delivered hundreds of meals that had not been kept properly hot or cold for extended periods of time, increasing the likelihood of food-borne illness,” the Yolo County district attorney’s office said in a statement Monday.

The business used the popular Chinese app WeChat to market its homemade Chinese food to Chinese foreign exchange students at the University of California, Davis, authorities said.

A health investigation began after several students reported becoming sick.

The business owner, Xin Jiang, agreed to settle a civil enforcement action by paying nearly $107,000 in costs and penalties. The agreement was approved by a judge last month.

Jiang admitted wrongdoing and is no longer operating Anna’s Kitchen but he could face another $90,000 in penalties if he reopens it or is found selling any type of food without a valid county permit, the DA’s office said.
