for those not familiar with US agriculture and food related stuff
let me share some insight to all forumer here
for beef alot country has BANNED US beef due to use of growth hormones and antibiotic in U.S. livestock, technically australian beef has less trace of antibiotic and hormone in them.
(so now you know what you should buy)

for chicken also BANNED due to the chicken is rinsed with disinfectants, including chlorine.

for soya bean /oat  BANNED is alot place due to GMO (genetically modified organism) seed , the reason is the seed company sold farmer every season a new batch of seed so that
they can earn alot money from it, if you replant the seed from the last batch of harvest you will get at least 30% less harvest thus causing you lose money.
not to mention US soyabean are more expansive then south america neighbor

for cereal , US food regulation is much worst then you think , they put alot BANNED substance such as Synthetic food dyes in it so that this kind of process food look much more colorful and vibrant
the above mention are LEGAL is US state but not everywhere in the world , even EU banned those product.
if you saw the same brand that available in US or EU chance are the ingredient list for both of them are not the same.
so dont think everything from US is a good thing.
