A foul stench across Merseyside is still lingering on after it was first reported last Friday.
People living and visiting Birkenhead , Wirral appear to be the worst affected by the odour and are still 'suffering' five days on.
The aroma was at first reported in Liverpool city centre with many describing it as smelling like "manure" and "off milk".
However, while the smell appears to have faded in Liverpool, those in Wirral are still suffering with the smell.
Diane Jones, 65 from Prenton said that she hasn't been able to open her windows for the last couple of days due to the odour being so bad.
She told the ECHO : "I can't open my windows because it makes me want to bork.
"It's been bad for days now.
"It does calm down in the night, but it picks back up again.
"It's affecting my breathing and has been doing me really bad."
Last night people also took to social media to voice their concerns.
One Twitter user, @_eeelliot said: "What is genuinely going on with the smell on the Wirral."
Another user, @sindenadam added: "There's that disgusting smell in the air again.
"Why is this still happening when it has clearly been reported #wirral #disgustingsmell."
A third user, @fordybeard said: "The manure smell is back in Birkenhead, what on earth is it?"
A fourth user, @AdamPot80902393 also noticed the smell in Upton and Moreton area, they said: "What is the terrible smell is over Moreton, Upton Village and Bidston tonight?
"Smells like manure/off milk and it's really strong."
Last Friday a spokesperson for Wirral Council said the smell plaguing the area was likely due to the agricultural spreading of biosolids.
Biosolids are organic manures produced by the treatment of waste water.
Farmers use these as an organic alternative to manufactured fertilisers.
Today, a spokesperson for Wirral Council said: "The latest is there is no update to the situation.
"The strong belief is that this is agricultural work.
"While there is little we can do to immediately stop the smell, we will write to local farms to remind them of their responsibilities under the Code of Good Agricultural Practice for such activities, which are designed to minimise odour."
A spokesperson for Liverpool Council said: "There have been no complaints that we're aware of."
