I had a remarkable revelation in the supermarket the other day. As I was browsing the fresh produce aisle as I always do when in a supermarket, I noticed something that really caught my eye.

It was actually quiet refreshing for a change. Reviewing each of the labels on the citrus products, they were clearly marked with the chemicals/fungicides that had been applied to the skin of the oranges, lemons, limes and mandarins. A few weeks back I was wondering if the pesticides that were used in growing carrots were highlighted on the pack would we change our behaviour?
And how is it that it comes down to the organic farmer to prove his/her produce is chemical free, why doesn’t the conventional produce list all the chemicals used in the growing of the crop? Well at least with citrus fruit we have the post-harvest treatments clearly outlined, this is the law in the EU.
It was quite a timely consideration as during the week we had one of our annual organic inspections and we were informed a sample of our produce will be sent away for screening for a mind-blowing list of chemicals (870 last time), more on that at a later date.
Anyway, back to the oranges. I am not sure that many people notice the chemicals though as it is hidden away in small print, nevertheless showing all these postharvest fungicides and wax treatments is a very good thing, as we can make more informed choices about our food. It is also worth noting that it is stated on all the labels that the skin is not suitable for eating!!
Here are some of the chemicals I found on the labels and their scientifically linked safety considerations. Also this is for an individual chemical most of the fruit I examined at up to 4 different treatments per piece of fruit.
1) Imazalil: Possible endocrine effects. The EFSA (European food safety authority) has evaluated imazalil repeatedly; the substance has raised endocrine/ecotoxicity questions in the past. Carcinogenicity concerns: possible/likely carcinogen based on animal data.
2) Thiabendazole EFSA peer-review concluded thiabendazole can affect thyroid hormone systems in animals. That is an important regulatory finding. Carcinogenicity/reprotoxicity: animal studies have shown some reproductive/developmental effects at high doses.
3) Pyrimethanil: Some experimental studies show reproductive or developmental effects in animals at high doses.
4) Fludioxonil: EFSA identified fludioxonil for endocrine-related effects.
5) Boscalid: It can be persistent in the environment
6) Azoxystrobin: Some studies indicate potential for oxidative stress and endocrine-related effects in experimental systems.
I am sure there are more, and this excludes the waxes that are also used to coat most conventional citrus fruit.
Not an entirely benign concoction, and not a cocktail of chemicals that I would particularly like to have on my food, thank you very much. I am sure you are wondering how an orange is not suitable for vegans. Well, one of the waxes that can sometimes be used, in particular E904 or Shellac (this is a resin secreted by a bug!), make the fruit unsuitable for vegans!
So, if you do buy conventional citrus fruit, please note again that it is advised that the skin is basically inedible or unsafe due to these chemicals (read the labels it actually states it there) so please don’t use the zest for cooking, much better to choose organic, and if you want to steer clear of these and other chemicals better where you can to choose organic entirely.
As always thank you for your support
