Ruby Walsh says horse racing's image has been damaged by the raid on a Kildare farm last week.
The 11-time champion jockey also believes his father Ted's reputation has been damaged because he was present at the premises raided by Department of Agriculture officials.
Animal remedies were seized during the raid on a farm, where equine therapist John Warwick was operating, near Monasterevin last Tuesday.
It was led by Department of Agriculture, Food and the Marine (DAFM) officials supported by gardai as well as Irish Horseracing Regulatory Board (IHRB) staff.
Walsh believes that testing of his father’s three-year-old horse by the Irish Horseracing Regulatory Board's head of anti-doping will not show anything suspicious, with Ted Walsh denying any wrongdoing.
Ruby told RTE 2fm's Game On: "Of course it’s damaging reputation wise for racing and for everybody that has been named in the piece.
"Dad was there, he has explained exactly why he was there for laser treatment on a horse’s tendon.
"To me, it’s like anything, there was a scene of a crime, to me he was an eye witness. Some people will think he was complicit and you'll never change their opinion.
"Unfortunately that’s what happens when you are there. I do believe he was an eyewitness."
Speaking to RTE over the weekend, Ted outlined that he was present at the farm in order to get laser treatment performed on a young horse with tendon damage.
He said: "It's a bad old thing for racing. I’m sorry that someone as high profile as me in racing was even there.
"To cast a shadow on the game - I can’t do anything about that now. I drove in, I was there.
"I rang the man in question a week or 10 days ago to ask the man when he was coming to Ireland again and he said he'll be there the next Tuesday, in the usual place.
"I drove down Tuesday. The horse had a slight tendon injury and he had done similar jobs on horses for me before, most notably Seabass, who was second in the National, who got a tear on a tendon.
"That normally means rest, a lot of rest, but if you want to get a horse back a bit quicker… this guy scanned it and lasered it and got him back in six months rather than 12 months."
He added: "I knew, as the fella says, 'wrong place, wrong time'.
"I knew there was plenty of action going on. It would have been a lot easier if I wasn’t there…. You’re always half guilty by association if you’re in somewhere, aren’t you?"
