Meat, dairy and sugar grown in a lab could be on sale in the UK for human consumption for the first time within two years, sooner than expected.

According to BBC, the Food Standards Agency (FSA) is looking at how it can speed up the approval process for lab-grown foods.

Such products are grown from cells in small chemical plants.

UK firms have led the way in the field scientifically but feel they have been held back by the current regulations.

Dog food made from meat that was grown in factory vats went on sale in the UK for the first time last month.

In 2020, Singapore became the first country to authorise the sale of cell-cultivated meat for human consumption, followed by the United States three years later and Israel last year.

However, Italy and the US states of Alabama and Florida have instituted bans.

The FSA is to develop new regulations by working with experts from high-tech food firms and academic researchers.

It says it aims to complete the full safety assessment of two lab-grown foods within the two-year process it is starting.

But critics say that having the firms involved in drawing up the new rules represents a conflict of interest.

The initiative is in response to concerns by UK firms that they are losing ground to competition overseas, where approvals processes take half the time.

Prof Robin May, the FSA's chief scientist, told BBC News that there would be no compromise on consumer safety.

"We are working very closely with the companies involved and academic groups to work together to design a regulatory structure that is good for them, but at all costs ensures the safety of these products remains as high as it possibly can," he said.

But critics such as Pat Thomas, director of the campaign group Beyond GM, are not convinced by this approach.

"The companies involved in helping the FSA to draw up these regulations are the ones most likely to benefit from deregulation and if this were any other type of food product, we would be outraged by it," she said.

The science minister, Lord Vallance, took issue with the process being described as "deregulation".

"It is not deregulation, it is pro-innovation regulation," he told BBC News.

"It is an important distinction, because we are trying to get the regulation aligned with the needs of innovation and reduce some of the bureaucracy and duplication."

Lab-grown foods are grown into plant or animal tissue from tiny cells. This can sometimes involve gene editing to tweak the food's properties. The claimed benefits are that they are better for the environment and potentially healthier.

The government is keen for lab-grown food firms to thrive because it hopes they can create new jobs and economic growth.

The UK is good at the science, but the current approvals process is much slower than in other countries. Singapore, the US and Israel in particular have faster procedures.

The FSA says it will complete a full safety assessment of two lab-grown foods within the next two years and have the beginnings of a faster and better system for applications for approvals of new lab-grown foods.
