A pet food supply company has warned of the biosecurity consequences when greyhound racing is banned in NSW from July 1, 2017.
A major family-run greyhound pet food supplier has warned of serious biosecurity issues when they close because of NSW's greyhound racing ban.
Rebecca and John Pace run Luddenham Pet Meat, about 70km west of Sydney, which is also a knackery.
About 95 per cent of their trade is supplying tens of thousands of kilograms of fresh meat per week to greyhound owners and trainers throughout NSW.
Ms Pace said local horse owners and farmers will have nowhere to take their animals to be humanely euthanised when they, and several other knackeries, close because of the greyhound racing ban.
"This decision will close all licensed New South Wales knackeries - there's about five of us which supply the greyhound industry - there is no other option for us," Ms Pace told AAP.
"The government have not thought about the biosecurity effect of all the unwanted livestock and where they go ... and that's hundreds and hundreds of horses, especially in the Sydney basin.
"A lot of Sydney councils will not allow you to bury horses on your property and the knackeries are the only place to bring your aged, ill or injured horses to have them humanely put down. That's a major issue."
The Paces are hoping that the Baird government will re-think its decision to ban greyhound racing in NSW from July 1 next year.
Not only will trainers be out of a job but so will the Paces when they shut their 50-year-old business.
Mr Pace's parents started Luddenham's in the 1960s and he and Mrs Pace were intending to hand it down to their two children who are learning the trade.
But Mrs Pace said the business, which has been built on reputation and quality, will close unless there is a change of heart.
"We employ about a dozen people but then you have the truck drivers, the livestock suppliers, meat suppliers and so on, they will all be affected," she said.
"Six people do the wrong thing (in NSW) and we all suffer."
Mr Pace said he was expecting the NSW government to heavily regulate the industry but felt it went too far in tackling the animal cruelty within the sport.
"I've been doing this for 40-odd years and I know owners and trainers who would go without a meal before their dog did," Mr Pace said.
The Baird government announced on Thursday it was shutting down greyhound racing in NSW because of evidence of systemic animal cruelty within the industry.
The ACT has also followed NSW but Queensland and Victoria say the sport will not be banned.
