New concerns about traces of a potentially harmful drug found in some British eggs have been raised by an organic farming group. The Soil Association says nearly one in eight egg samples tested contained traces of the antibiotic lasalocid. It claims the drug could pose a risk to people with heart conditions. The Food Standards Agency says the levels reported do not raise immediate health concerns but has criticised the poultry industry over the finding. The food safety watchdog said it was disappointed the industry had not eradicated the drug from eggs.
