Bovine TB is an on-going problem for many farmers in Wales.
It's an infectious disease that can be passed on from badgers.
The Welsh Government has carried out a consultation on what should be done to control its spread but the results have not yet been published.
One farmer says the uncertainty is tough for his business.
Mark Williams has farmed near Welshpool for years.
It's a rewarding job but a hard one, made tougher by the presence of bovine TB.
95% of Welsh cattle herds are now TB-free.
Areas like mid and West Wales still face outbreaks of the disease.
Under new plans, the Welsh Government proposes dividing Wales into areas of low, medium and high TB outbreaks.
Places with repeated cases would be given their own 'action plans', and may face stricter controls.
In certain cases, badgers - a major carrier of TB - could be trapped and culled where it can be proven they have the disease.
In recent years, the focus has been on trapping and vaccinating badgers instead.
Wildlife groups say this is still a better option.
Farming unions want a change in policy, but warn the consequences of any new plan will be felt for years.
