Rakthong Mada, 52, said they had bought mussels from the shop on December 4, and though her husband Charoen, 56, ate a few, their son Watchara, 35, feasted on them.
The following morning, Watchara showed symptoms of food poisoning and his father give him some medicines to help. Rakthong said she later started vomiting so much that she had to be taken to hospital.
Watchara later called to say he was getting worse and followed her to hospital. However, doctors were not able to save him and he died later in the day.
The family said it has decided not to take legal action against the shop, but will discuss the case once Watchara’s funeral rites are completed.
