Lincoln MP Gillian Merron presenting Lincolnshire sausages to the then Chancellor Gordon Brown in 2006.
A campaign to protect the identity of the Lincolnshire sausage has been taken to Downing Street.
Lobbyists have submitted a petition to Number 10 in a bid to safeguard the recipe of the county's favourite banger.
The petition calls for the Prime Minister to "support Protected Geographical Indication status for Lincolnshire Sausages".
The aim is to make sure only an approved recipe can be made by county producers, meaning a boost for local traders.
It has been put forward by Janet Godfrey of the Lincolnshire Sausage Association.
She said: "PGI status for Lincolnshire sausages would mean that they could only be manufactured in the historic county of Lincolnshire according to the specified criteria.
"This would support the numerous small producers that we have in the county and prevent inferior products from reaching the market."
Supporters will be able to sign the petition online until November 6.
The call for support follows a five year fight started by the Echo to protect the Lincolnshire sausage by European law.
Since the Save Our Sausages campaign began, MPs and Ministers have given their backing to the campaign – including Mr Brown himself who tucked into a breakfast of Lincolnshire sausages on Budget day when he was Chancellor.
Campaigner and butcher at Lincoln's Elite Meats Kenny Roberts said: "We're hopeful that if we get the Prime Minister's support it might help sway Defra to make the decision we're all after.
"I'll be putting up signs in the shop and letting people know about it when they come here, so there is a good chance we'll get a lot of support."
