Partly because of a one-day quarantine of two barns, the Gulfstream Park Rainbow 6 paid just $51.34 on a 20 cent-only bet on Wednesday.
That was one of the ten-lowest payoffs on the Rainbow 6 since HorseRacingFLA began tracking Gulfstream handle in August 2015.
Gulfstream put the two barns under quarantine on Tuesday night, after a horse in one barn was euthanized because of neurological problems.
According to a report in Bloodhorse, Gulfstream put the barns under quarantine as a precaution because of concern that the horse might have been infected with EVH-1. That is an equine herpes virus that is contagious and can result in respiratory and neurological disorders.
On Wednesday afternoon, Gulfstream determined that the euthanized horse did not have EVH-1, and it lifted the quarantine.
Last weekend, two horses in Maryland, including one at Laurel Park, were detected with theVH-1 virus.
The Laurel, Md., track put two barns under quarantine and has cancelled its race card for Friday.
Laurel Park and Gulfstream are owned by The Stronach Group. Because of Laurel's cancellation there will be no Stronach 5 bet on Friday. That $1 minimum bet is offered on most Fridays--with races at Gulfstream, Laurel and either Santa Anita Park or Golden Gate Fields.
On Wednesday, the ten-race card at Gulfstream had fourteen scratches with most of them attributable to the quarantine.
There were only 36 horses in the six Rainbow 6 races. Four winners were even-money or lower, one was 5-2 and one was 9-2.
Program numbers of the winning horses were 6-5-4-2-7-2.
Wednesday was the start of a new Rainbow 6 cycle, following a mandatory payout on Sunday.
Betting on the Rainbow 6 was $172,272. Gulfstream took our 20 percent, divided 56 percent among tickets with six winners and put 24 percent into a new carryover.
HorseRacingFLA's review of Equibase charts indicates there were 1,879 winning tickets.
Gulfstream has a ten-race card on Thursday with first post of 1:10 p.m. The Rainbow 6 will be on races five through ten with the sequence scheduled to start at 3:11 p.m.
