Out of nowhere we've had a succession of very low FPD tests in our milk in May,we get the occasional one if the parlour hasn't been drained properly but when 503,504 turn up as results we started to jump about.It's not the bulk tank or tank washer,we take pains to drain every drop from the plant and we've decided against it being that since another low result turned up yesterday so we think it has to be the plate cooler even though no water comes out where it shouldn't when we turn the tap on to check.We've bypassed the cooler yesterday and await today's test result to see but I wondered if anybody had experienced problems with plate coolers that were very hard to detect or if it proves not to be the plate cooler if such low numbers can occur naturally?(How much water do these figures equate to is also hard to identify..) Our milk buyer penalises us 20ppl for an FPD 508 or below so given the way the winter's been losing several days milk from a better month is going to be ruinous if we can't sort it out..
