Chinese distillers have been spiking their booze with Sildenafil, better known as Viagra, and are often marketing them for their extra health “benefits”.

The makers called their products “Kungfu Alcohol” and “Life-nourishing Liquor”, among other labels, authorities in the southern region of Guangxi said at the weekend, adding they had seized more than 5,300 bottles and almost 1,200 kilograms of additive chemicals. The total value of the confiscated product is about 700,000 yuan (almost $113,000).

While adding a little Viagra to booze may sound like an amusing antidote to The Bard’s timeless observation that drink “provokes the desire, but it takes away the performance”, (Macbeth, Act 2, Scene 3), China takes food contamination seriously.

Baijiu is a fiery grain liquor that commands high prices in China.

China’s food traceability systems and regulation were classified as “poor” in a 2014 report from the Institute of Food Technologists, with the lowest score of around 20 countries in the survey.

The administration said in June, state media said Chinese customs have seized around 483 million dollars worth of smuggled meat, some more than 40 years old and rotting.
