STOCK WATCH

PHARMACEUTICAL firm Eco Animal Health hit an all-time high yesterday after winning approval for a drug to treat chickens laying eggs for human consumption.

The drug, used to treat chickens infected with a bacteria called Mycoplasma, was approved by a Malaysian pharmaceutical regulator.

Eco will pursue approval for the drug in a number of other markets, after winning a European licence in June last year.

Shares in the firm rose 1.7pc, or 10p, to 615p.
