The Daily Telegraph reported on Monday (March 9) tuna and mackerel from the cannery was being held and tested by Australia's Agriculture Department.
The factory, owned by ISA Value Co Ltd, supplied tuna for John Bull tuna products used by the Soul Origin Cafe near Town Hall station. The product was suspected of causing scombroid poisoning.
The Daily Telegraph, which sent a team to Thailand to conduct the report on the factory, as well as those of other companies, said the tightly guarded factory employed 3,000 migrant workers.
The report said some unlabelled products were kept in open warehouse when temperature was 34 degrees Celsius. Some workers also claimed the tuna room was smelly and messy.
The team also interviewed some workers who indicated possible use of child labour at some tuna factories.
FTA Food Solutions, the Victoria-based manufacturer of the John Bull catering-tuna brand, said it sourced tuna from the factory, which it said meets globally recognised standards used in Australia.
An ISA Value spokesman said the firm had sent products to be tested, which could take a week, and would not hesitate to take action once the results came in.
ISA Value is one of the two subsidiaries of Sea Value Plc. The other is Unicord Plc, which also processes tuna. The group has many brands of tuna products including Super-C-Chef for the local market. It also makes pet food.
Thailand was downgraded in June last year to the lowest level in the US State Department's Trafficking in Persons report, alongside Iran, North Korea and Saudi Arabia in its treatment of workers and the way it protects them from abuse.
The downgrade came after a Guardian report found that slaves forced to work on Thai fishing boats for no pay were integral to processing prawns sold in the US, UK and elsewhere in the EU by industry giants including Tesco, Walmart, Carrefour and Costco.
