Je pravda, \u017ee p\u0159i z\u00edsk\u00e1v\u00e1n\u00ed bun\u011bk, do kter\u00fdch se p\u0159enesl \u017e\u00e1dan\u00fd gen, se n\u011bkdy jako technick\u00e1 pom\u016fcka k n\u011bmu p\u0159id\u00e1val tak\u00e9 gen ru\u0161\u00edc\u00ed \u00fa\u010dinek ur\u010dit\u00e9ho antibiotika.

Pro neinformovan\u00e9 spot\u0159ebitele to zn\u00ed varovn\u011b. Jen\u017ee jak\u00e1 je skute\u010dnost.

Agit\u00e1to\u0159i zaml\u010duj\u00ed, \u017ee 5 a\u017e 50 % z nich nese geny necitlivosti na antibiotika.

Naopak p\u0159ed\u00e1v\u00e1n\u00ed gen\u016f mezi bakteriemi je b\u011b\u017en\u00e9.

Ale v jednom na\u0161em \u010dasopise psali o takov\u00e9to nechutnosti:<\/strong><\/p>\n

Ti \u0161\u00edlen\u00ed v\u011bdci dali do jahody dokonce ryb\u00ed gen!<\/strong><\/p>\n

Skute\u010dn\u011b 25. \u010dervna 2008 v jist\u00e9m na\u0161em \u010dasopise pro \u017eeny jist\u00e1 d\u00e1ma uve\u0159ejnila tuto radu: \u201eU citliv\u011bj\u0161\u00edch lid\u00ed mohou jahody vyvol\u00e1vat alergie. D\u016fvody: Jedn\u00e1 se o GMO (geneticky modifi kovanou potravinu), do jahod b\u00fdv\u00e1 v tomto p\u0159\u00edpad\u011b vlo\u017een gen ryby.<\/p>\n

A jestli jste alergi\u010dt\u00ed na mo\u0159sk\u00e9 potvory, probl\u00e9m je nasnad\u011b.\u201c Je to obrovsk\u00fd \u00fasp\u011bch v systematick\u00e9m ohlupov\u00e1n\u00ed ve\u0159ejnosti, kter\u00e9mu d\u016fv\u011b\u0159iv\u00e1 autorka podlehla. Co je za t\u00edm? V USA rann\u00ed mraz\u00edky ni\u010dily plant\u00e1\u017ee jahod. Za to mohou krystalky ledu vytvo\u0159en\u00e9 v bu\u0148ce rostliny a naru\u0161uj\u00edc\u00ed jej\u00ed strukturu. Arktick\u00e9 ryby \u017eij\u00ed ve vod\u011b o teplot\u011b (d\u00edky soli) pod bodem mrazu. Aby nedopadly jako jahody v Kalifornii, tvo\u0159\u00ed b\u00edlkovinu, kter\u00e1 podchlazen\u00e9 vod\u011b v bu\u0148ce zabr\u00e1n\u00ed vykrystalizovat. Proto \u0161lechtitel\u00e9 p\u0159enesli p\u0159\u00edslu\u0161n\u00fd gen do jahod, a ty pak skute\u010dn\u011b mraz\u00edky dob\u0159e sn\u00e1\u0161ely. Takov\u00e9 jahody se jinde ne\u017e v Kalifornii nep\u011bstuj\u00ed a nejsou jinde povoleny pro trh. Velice t\u011b\u017eko je mohla doty\u010dn\u00e1 d\u00e1ma potkat.<\/p>\n

Vsugerovat lidem p\u0159edstavu slane\u010dka v jahodov\u00e9m d\u017eemu je velmi vhodn\u00fd n\u00e1stroj mision\u00e1\u0159\u016f v\u00edry ve \u0161kodlivosti GMO. Pikantn\u00ed na tom, jak jim naivn\u00ed lid\u00e9 nal\u00e9tnou, je to, \u017ee d\u00e1ma ob\u00e1vaj\u00edc\u00ed se ryb\u00edho genu (asi i mluv\u010d\u00ed Greenpeace, kter\u00fd tento n\u00e1stroj propagandy r\u00e1d pou\u017e\u00edv\u00e1) patrn\u011b s po\u017eitkem l\u00ed\u017eou jemnou zmrzlinu, kam se p\u0159id\u00e1v\u00e1 pr\u00e1v\u011b ona ryb\u00ed b\u00edlkovina vyroben\u00e1 bakteriemi s p\u0159enesen\u00fdm p\u0159\u00edslu\u0161n\u00fdm ryb\u00edm genem. P\u0159id\u00e1v\u00e1 se tam proto, aby se p\u0159\u00ed v\u00fdrob\u011b zmrzliny netvo\u0159ily velk\u00e9 ledov\u00e9 krystaly. Ty toti\u017e zp\u016fsobuj\u00ed pocit drsnosti, a proto jejich odstran\u011bn\u00ed \u010din\u00ed zmrzlina \u201ehladkou\u201c a jemnou.<\/p>\n

Tak\u00e9 jsou mision\u00e1\u0159i stra\u0161idel, kte\u0159\u00ed hl\u00e1saj\u00ed, \u017ee: <\/strong><\/p>\n

Uveden\u00fd p\u0159\u00edpad je tedy naopak p\u0159\u00edkladem seri\u00f3zn\u00edho p\u0159\u00edstupu k v\u00fdzkumu a aplikaci GMO.<\/p>\n
