Affco denies the claims.
In a pre-trial hearing in August last year, it was disputed whether WorkSafe had filed a charge in time.
Affco filed an application that the case be dismissed under these grounds. However, in December, Judge Tony Couch rejected Affco's application and the matter will now proceed to trial.
In his judgment, Couch said Wright "became infected while cleaning up spilled offal at the plant".
"As a result, Mr Wright became seriously ill and required surgery to replace a damaged heart valve."
A video conference with all parties will take place today to consider pre-trial applications made by Affco. A trial date is yet to be confirmed.
