A famous restaurant in Seoul, South Korea, must pay a fine after serving ants to customers. The owner put three to five ants on top of sorbet, a cold fruit dessert, to give the dish a sour taste.
on top of= 在……上面(放置或覆蓋於某物上方)
The restaurant broke the local food safety law. South Korea allows people to eat only ten types of insects, such as grasshoppers and silkworms. Ants are not on this list of approved insects.
such as= 例如;用於引出具體例子
Judges said the problem was serious because tests showed high levels of heavy metals in the ants. The owner said he did not know that serving ants was illegal in South Korea.
high levels of= 高含量的……(表示某物質數量或濃度很高)
