The Mexican government confiscated 10,000 gallons of illicit alcohol and raided 31 resorts and nightclubs in Cancun and Playa del Carmen that were thought to serve the counterfeit liquor to customers, it was reported on Sunday.

Authorities south of the border also shut down a lobby bar at the Iberostar Paraiso Maya hotel where a 20-year-old Wisconsin woman drank tainted alcohol, passed out, and drowned in a pool, the Milwaukee Journal Sentinel reported.

Another popular tourist establishment in Cancun, the Fat Tuesday bar, was also temporarily shut down by authorities.

The woman, Abbey Conner of Pewaukee, Wisconsin, was on holiday with her brother, mother and stepfather, at the Paraiso del Mar hotel near Playa del Carmen, Mexico, this past January when the incident took place.

She had been swimming in the pool with brother Austin, 22, when they went to a swim-up bar and were offered a shot along with another group.

Austin said he remembers swimming around for a little while after that, and then suddenly 'the lights went out'.

Both were found floating in the pool some time later - Abbey face-down and not breathing, and Austin with a large lump on his head and severe concussion.

They were taken to hospital where Abbey was stabilized before being flown back to Florida for further treatment.

But shortly afterwards doctors found she was brain-dead and the decision was made to turn off her life support.

The crackdown comes weeks after the State Department warned tourists of possibly tainted alcohol being served in Mexico. This past January, Abbey Conner, 20 (left), and brother Austin, 22 (right), passed out in a hotel pool while on vacation at a resort near Playa del Carmen

The Conners were among a number of visitors to the same resort who reported blacking out after drinking small or moderate amounts of alcohol.

The rash of incidents prompted the State Department last month to warn American tourists traveling to Mexico to beware of tainted alcohol.

Mexican officials announced the confiscations during a news conference on Friday.

Iberostar, which owns the hotel where Connor died, said it adheres to strict regulatory standards and only purchases 'sealed bottles (of alcohol) that satisfy all standards required by the designated regulatory authorities.'

The family are now suing the hotel company, saying they are refusing to cooperate with the investigation into their daughter's death.

Connor’s mother, Ginny McGowan, praised the Mexican government for the crackdown.

'This is awesome; this is huge,' she said.

'It’s needed. There is obviously stuff going on that needs to be cleaned up and looked into further,' said McGowan.

'They need to investigate and interview employees. This makes sense. This needs to happen.'

Since 2010, the Mexican government has seized over 1.4 million gallons of tainted alcohol from a variety of business establishments, including local bars, hotels, and other entertainment venues, according to a government report.

The seizures were prompted by a years-long problem whereby counterfeit alcohol has been sold or produced at considerable health risk to those who consume it.
