Dodgy condoms with Durex branding sold on the deals website, Groupon Australia, have been recalled.

The condoms, which include branding of Durex's "Extra Safe," "Thin Feel" and "Performa" product lines, are counterfeit, and may come with serious flaws such as holes in the latex, according to the Australian Competition and Consumer Commission's (ACCC) Product Safety Recalls website.

The Therapeutic Goods Administration (TGA) also put out an alert on Wednesday, advising consumers and health professionals to be wary.

Anyone who bought the products off Groupon between 12 March, 2015 and 10 April, 2015 is told to get rid of them. As the ACCC helpfully points out, the faulty condoms "may not prevent pregnancy or protect users against sexually transmitted diseases."

Let's hope no one finds out the hard way.

A spokesperson from Groupon confirmed to Mashable Australia the condoms were counterfeit, defective goods. "Customers are our utmost priority at Groupon and we take their health and safety very seriously. All customers who purchased the counterfeit products have been proactively contacted by Groupon notifying them of the recall and have been advised to discontinue use immediately, dispose or return the goods, and seek professional medical advice if they have concerns about their health. A full refund has been processed to all customers."

Groupon's Merchant Review Policy promises it does due diligence on potential sellers.

When asked whether the merchant, in this case, Citrus Beat, was properly reviewed, or whether the company could potentially be liable for unexpected pregnancies resulting from the faulty condoms, Groupon's spokesperson said ongoing investigations into the matter were underway.

The TGA said counterfeit condoms are a serious problem for leading brands, including Durex. China, in particular, has been producing millions of fakes. Raids in the country's Fujian province in 2013 turned up more than 2 million condoms wrongly labeled as Durex, among other brands.
