The Telegraph said:
The Queen's horse Estimate tested positive for morphine because poppy seeds "appear" to have contaminated its food, according to the company that supplied it.
Royal Warrant holders Dodson & Horrell said its own investigation suggested the contamination did not occur at its own horse feed manufacturing site, and that its inquiries were now centred on its supplier.
The news is unlikely to affect the consequences of the positive test, as the British Horseracing Authority (BHA) has a zero tolerance approach to morphine on race days.
Yeh right, if the nag would not belong to Her Majesty the breeder would just be banned for life without any other discussion.
