Students picking up food in UC Berkeley dining commons are now required to show that they are compliant with campus COVID-19 testing requirements. Beginning Monday, to check for compliance, student employees known as health ambassadors have started to use an online eTang badge system that assigns colors according to the student’s testing status, according to an email from Cal Dining and Cal Housing. Students will be required to use their phones or a provided iPad to show their badges. A green badge indicates the student has been testing negative for COVID-19 twice a week, and they will be allowed into the dining hall. Those with orange or red badges, or yellow badges after Feb. 8, will have pre-packaged meals brought out to them instead, according to campus spokesperson Adam Ratliff.
