Im an ex organic farmer. If its a NZ product and has bio-grow or assure quality certification then there will be no nasties in it. Its pretty rigorous. Paddocks are even tested for historical chemicals.
On saying that, the real benefit of organics- supporting it- is environmental. And mainly relates to insect and bird life, Water quality etc. which are more effected by chemical residues.
The conventionally farmed food you eat thats gone through a meat works or dairy company in NZ has such high restrictions on chemicals in the product that there really is no difference between that and organics.
Objectively the only other difference might be a slightly better quality product as organic farmers tend to have a lower stocking rate and need to have a higher level of care for the stock.
