The breakfast at the construction site cafeteria where the incident occurred was relatively simple, consisting mainly of vegetable soup, steamed buns, and pickled vegetables.
The pickled vegetables had already been checked on-site. They were all sealed in bags and poured out after being cut open.
As for why they didn't buy the relatively cheaper bulk pickled vegetables, according to Wu Guichun, he would have to cut them himself, and with few hands, hiring an extra person wasn't cost-effective, so they bought the bagged pickled vegetables.
Moreover, pickled vegetables aren't free; the workers eating breakfast pay for however much they consume based on a few steamed buns, bowls of porridge, and pickled vegetables.
Since the pickled vegetables were bagged, it was practically impossible for them to contain pufferfish toxin.
