There is almost no evidence that even 300g of meet can trigger a positive test.
The full text of the oft-cited Bizec paper that supposedly shows evidence that uncastrated boar meat can lead to a doping positive is linked below. It shows:
* A total of three subjects (men) participated in the study.
* Of 27 urine samples, one single sample from one man exceeded 4ng/ml (see figure 7 on page 4).
* Each of the 3 men ate more than 3/4 of a pound of meat from a single uncastrated Pietrain boar -- including roughly 25% from the kidneys, 25% from the heart, and 25% from liver.
* The Pietrain boar breed has numerous disadvantageous for breeders, so "is not or rarely used for production purposes. Their use is only limited for the crossbred and synthetic terminal breeding. Only a few pigs are used to supply stock for breeding programs." (See second link, below.)
* The 21-year old study was published in the journal "Rapid Communications in Mass Spectrometry" which has an impact factor of 2.2 on a scale of 0+ to 10+.
