many (like me) had bse
cows, but none of these were ever treated with OP's (even in utero).

They were bred from cows that were.

means nothing. Virtually every organic dairy cow in the country at the
moment is bred from cows treated with OPs

'The lack of BSE incidence in beef suckler herds (1)

who in the UK are normally the daughters of dairy cows who of course
were treated with OPs

It says 'lack', not 'total lack'.

'2.8 Dairy herds were far more affected by BSE than beef herds.
The recorded incidence among dairy herds between 1 April 1985
and 31 March 1988 was 311 out of 44,767 herds (0.69 per cent),
considerably higher than the incidence in beef suckler herds
(11 out of 54,166 herds, or 0.02 per cent). 9 This was probably due
to the lower levels of concentrate feeding in beef suckler herds, 10 '

(8) Section 4.8.3.2 ( page 36)

"FURTHERMORE, BEEF COWS WHICH OBTAIN MOST OF
THEIR FOOD FROM PASTURE , ARE MORE LIKELY THAN
DAIRY COWS TO EXPERIENCE AN ABNORMAL IMBALANCE
IN DIETARY INTAKE OF THE TRACE ELEMENTS COPPER,
MOLYBDENUM, SELENIUM AND MANGANESE, SINCE
COMPOUND FEEDS FOR DAIRY COWS ARE SUPPLEMENTED
WITH THESE TRACE ELEMENTS AS NECESSARY TO MEET
NUTRIENT REQUIREMENTS. ACCORDINGLY, A HIGHER
INCIDENCE OF BSE WOULD BE EXPECTED IN BEEF COWS
RATHER THAN IN DAIRY COWS. THE REVERSE IS TRUE."

and total lack of BSE in home reared cattle on organic farms (87)

who is the UK are almost all daughters of conventional cows who were
treated with OPs

It says 'home reared'.
