It follows concerns changes proposed by the UK's Food Standards Agency (FSA) could undermine the "scores on doors" scheme in Wales.
In November 2013, Wales became the first UK nation to require food outlets to display their inspection ratings.
The FSA is considering allowing third party auditors to be brought in to make much more limited inspections of premises.
Senior officers in Wales are concerned the changes are fuelled by a need for councils in England to make savings - something the FSA has denied - and believe they would undermine the improvements in Wales.
Mark Elliott, from the Directors of Public Protection in Wales, said: "We should in Wales really consider a Wales-specific solution now, to build on what we've done, and not mess up what we've already got."
The FSA said the proposed new system would give a better picture about a premises' standards every day - rather than just on the day they are inspected - by taking their own audits and systems into account.
It has also been suggested food businesses should have to pay for a licence before they could open.
A Welsh Government spokesman said: "We will continue to collaborate with the FSA and local authorities to develop a sustainable approach to food business regulation that works across Wales and which reflects the need to ensure that the highest standards of food hygiene and safety are maintained."

Student Melanie Road was 17 when she was attacked as she made her way home from a night out in Bath in June 1984. Her body was found in front of garages.
Christopher Hampton, 63, of Staple Hill, Bristol, appeared before the city's crown court earlier on Tuesday.
Mr Hampton was remanded in custody and told he will face trial on 9 May next year.
The father-of-three, who is being held at HMP Bristol, spoke only to deny the single charge of murder.
Prosecuting, Kate Brunner QC told the court the trial was expected to last up to four weeks.
Melanie had been out with her boyfriend and friends to the Beau Nash, a nightclub in Kingston Parade.
She left the club at 01:30 BST on June 9 and was last seen alive by her friends a short time later in Broad Street.
Last year, Melanie's mother Jean and sister Karen spoke about the impact the murder has had on them.
Mrs Road wrote an open letter to coincide with the 30th anniversary of her daughter's death, appealing for anyone with information to come forward.
Calls have been made for Wales to have greater control over food hygiene.
