A new report says that the presence of microplastics in seafood has been overstated by the media. The paper, by researchers at Heriot-Watt University, says although media reports tended to concentrate on seafood contamination, the levels of microplastics in seafood is no greater than in other foodstuffs. It also says that dust and indoor air contain more microplastic particles than food.

All week, we're taking a closer look at county council tenant farms. These farms have traditionally been a first step on the ladder, often for young aspiring farmers to get a foothold in agriculture. However county council tenancies have become harder to find and in recent years many cash-strapped councils have sold off a significant number of their farms. Not so in Staffordshire, where one young farmer Tom Chapman is building up his herd of sheep after securing a tenancy.

Farm machinery manufacturers who export to the United States say their trade is being made 'almost impossible' after tariffs on steel and aluminium were extended. Originally tariffs on steel and aluminium were just for bulk items, but now, if a UK-made tractor is exported to the US, every steel or aluminium component - down to individual nuts and bolts - has to be taxed on the basis of where it came from, so the correct overall tariff payment is made. We speak to the Agricultural Engineers Association.
