Dioxin Found in Imported Phenoxy Herbicides in Australia

There has been a monster fuss over dioxin in the phenoxy herbicides used in the 1970s.  Agent Orange, helicopters, defoliation.....Vietnam era one says.........the manufacturers do it better now.

The good ones do.............but with a race to the lowest cost product for the ultra competition which drives the cost issue in agriculture and horticulture in Australia..............guess what?  Imported product has suddenly appeared on the scene with plenty of dioxin present as a by product of the production of technical grade 2,4-D and 2,4,5 -T.  Same  quality control issue as the 1970s, one would suspect.

Phenoxy herbicides are not banned and many do a great job at low rates, and modest cost.  Combination products are widely used - eg 2,4-D and MCPA or dicamba, and often in horticulture and even home garden use as turf herbicides.  2,4-D was probably the first real herbicide and has been used since the 1950s.

But the costs have fallen and there are many manufacturers in China, and some it now seems are really cutting corners.

Yes, Australia has probably not done enough monitoring of ongoing imported products either. 

As is often the case, initial supply is fine - meets specifications etc.  As volume goes up.......sadly, quality plummets!  Or a different lower cost producer replaces the decent producer who is meeting quality requirements and the exporter [ often not the producer] says little.......but quality is going down, but not enough to indicate the product is not doing its job. 

It is the by product that is the problem - dioxin.
Herbicide spraying - Vietnam war era.

It is deadly stuff.............look it up eg wikipedia, plenty of detailed reports on line.  It is VERY NASTY!

It is unclear how widespread the problem is in Australia, but some believe that it is not major, restricted to some importers and formulators using lower cost product to drive their sales into the market.  It might take some time to sort out, but as a guide.........BEWARE if using phenoxy herbicides.  You should be now anyway.

Everyone seems to have thought the dioxin issue was dead and buried.........and with quality technical product from quality manufacturers it broadly had not been an issue for many years.  However, it is back.

It is interesting to also speculate how much poor technical product also went into other Asian countries - Malaysia, Vietnam, Laos, Burma, Cambodia etc where cost is probably an even bigger concern.  They are unlikely to have respected regulators to get on top of this issue.

Is it any wonder many do not trust Chinese product?  Whether agricultural chemical or baby formula, seems immaterial - they are suspect, and one wonders why Chinese want our rural products???

Dioxin Contamination in Food Scare - Germany

China is often accused of lax process and poor management of industrial food processes. The contaminated milk powder scandal is but part of that.

This time it is Germany......and dioxin.

Same sort of issue, a company in this case it seems, opting for cheap ingredients for formulated animal feeds, with the material not suitable for animal use, but only for industrial use. The animal feeds were then used and the dioxin showed up in eggs, pork, etc.

The contamination is nominally small, really miniscule. But modern analytical techniques can detect very very small levels of some of these toxic products, and dioxin is certainly toxic. German authorities are playing it down, stating that levels are extremely low, and NOT a human health threat.......which is most probably true. But perception is EVERYTHING, and the public is very unhappy over the whole issue.

Food safety is a big issue, and Germany is a big organic market, so there are many consumers if not buying organic foods exclusively, do so at times. This will further inflame emotions over the "factory food" catchcry.

In reality............a shoddy, tawdry manufacturer, who it seems is under big pressure and may become insolvent over the issue.

There are many news items with this one a reasonable overview:

This will reopen questions about regulation or reregulation of food quality. Yet, in reality the problem WAS detected, and quickly dealt with. There will be recriminations, absolutely no doubt.
