The head of the National Farmers' Union (NFU) has said farmers are "furious" about the horsemeat scandal.
Peter Kendall said that shorter supply chains and better labelling of British meat would help prevent a repeat.
He added: "Our research also demonstrates the strong demand for British-farmed products, and so retailers, processors and food service companies have a responsibility to ensure there is clear country of origin labelling on the products that consumers purchase."
Initial tests on school meals in Worcestershire have found no traces of horsemeat.
The county council's specialist scientific services have been checking meals meet the required standard.
The scandal has resulted in a number of products being taken off supermarket shelves after they were found to be contaminated. The council says it will have the full results of the samples tested next week.
A decision was taken earlier this week to proactively test meal samples from a number of schools throughout Worcestershire and we expect to have the full results of this exercise next week.
The analysis on the initial samples are complete and Worcestershire Scientific Services can confirm that of the 8 samples so far tested, all are negative for equine (horse) DNA.

Having removed beef from the menu in the 350 schools in Staffordshire the council has said that they do expect to be serving beef after half term, which is next week:
We have every confidence in our suppliers, however while this story continues to be in the news it seemed sensible to offer an alternative meal, where beef is not Farm Assured and sourced in the UK.
As a council we are committed to promoting and using local produce as much as possible and are currently expanding a pilot scheme in schools where only meat from Staffordshire farms and this is being rolled out across the county.
While there is absolutely no suggestion that there is any problem with any of the beef supplied we wanted to take a belt and braces approach, but expect beef to see it back on the menu after half-term.
