Viewers accuse Channel Seven producers of deliberately planting a bone in a pasta dish on My Kitchen Rules

My Kitchen Rules viewers have been left questioning how a bone ended up inside a pasta dish on Tuesday night's episode.

Contestants Tiffany and Giancarlo hosted an Italian-inspired Instant Kitchen during the episode, serving up Agnolotti di Coniglio — a rabbit-filled pasta dish.

But as their co-stars tucked into the meal, Deanne made an unexpected discovery when she found a bone in the filling.

The discovery immediately put her off the dish, while another contestant raised concerns that it could have posed a choking hazard.

Viewers watching at home were also left puzzled by the discovery, given the steps involved in preparing the pasta filling.

The filling was placed into a food processor before being transferred into a piping bag and used to fill the pasta.

Some questioned how the bone had made it through those stages and into the finished dish.

'Oh come on, folks, reality TV planted. Think about it, how would a bone that size have got through a piping bag? Just disappointed because this is the only program enjoy,' one person sniped.

'That bone could not have gone through the piping bag without being noticed or clogging the hole. Producers added this in for a stir,' a second added.

'It was set up,' another suggested.

The claims were made by viewers on social media, and there is no suggestion that the bone was deliberately planted. 

Daily Mail has contacted Channel Seven for comment. 

The bone discovery also came up during the judges' feedback, with Colin Fassnidge taking a surprisingly relaxed approach to the find.

'It is what it is,' he said.

Colin described it as 'a peasant-style dish', saying that if he visited a nonna's house, he would be served a bowl of the food and remember it as 'amazing'.
