Bt loving insects

 When Indian cotton farmers started to complain that their GM, supposedly insecticidal, crops were being eaten by pink bollworm, toxin and all, Monsanto was quick to lay the blame on the growers and regulators. 

“Apparently, the pink bollworm resistance problem is due to farmer ignorance: failure to plant non-Bt crop refuges, failure to procure non-Bt seed for the refuges, failure to scout the crop for pest emergence, failure to switch to Monsanto's Bollguard II which has had two Bt genes inserted, over-use of pesticides, failure to manage the infected crop residues and unopened bolls after harvest, poor tillage and inadequate grazing of cattle on the GM stubble, and previous illegal planting of unsuitable Bt cotton crops.” (Bt RESISTANCE RIGHT ON CUE – March 2010)

Asking to change the world

When biotech industry lobbyists and the government ministers they were targetting found themselves faced with a GM-sceptical public, the answer was education, education, education. They convinced themselves that once the public understood that

• scientists know exactly what they're doing
• genetic transformation is a precise process
• GM food undergoes more testing and therefore is safer than any other food ...

However, the more education people got about GM food, the more their concern, unaccountably, grew.

Bt resistance right on cue

News archive: March 2010

In a statement issued on 6 March this year, Monsanto said: 

“Testing was conducted to assess for resistance to Cry1Ac, the Bt protein in Bollgard cotton, and pink bollworm resistance to Cry1Ac was confirmed in four districts in Gujarat – Amreli, Bhavnagar, Junagarh and Rajkot. Gujarat is one of nine (Indian) states where cotton is grown. To date, no insect resistance to Cry1Ac has been confirmed outside the four districts in Gujarat.”

'Bollguard' cotton is a GM variety developed by Monsanto. 'Bollguard' has been transfected with a variant of a gene copied from the soil bacterium, Bacillus thuringienses or 'Bt'. The toxic protein generated by the transgene kills a specific insect pest, pink bollworm.

Flu free fowl

February 2011

The latest UK research on GM is the creation of flu-free chickens.  In these novel birds, the dreaded H5N1 virus can't replicate as normal, doesn't infect the rest of the flock, and therefore, presumably, won't transfer to humans.

Avian flu continues to be a global health concern.  Although primarily a disease of wild birds, it occasionally infects poultry flocks in which it can spread like wildfire.  Controls, such as vaccination and bio-security measures, are complicated by the nature of the virus which is not a single type of virus, but exists in many subtypes and, like all flu, is an ever-evolving “master of mutability”.

Fears of a major outbreak of the virus in the UK in 2006 came after a swan, found dead off the coast of Fife, was discovered to be infected with H5N1.  The virus did not cross any species barriers in Scotland and the feared pandemic did not happen.

Why look out for GM soya?

February 2011

There's a very valid question surrounding GM soya: all the soya we eat is so heavily processed and artificial anyway, is it really any different in GM form?

Consider that soya beans themselves are rarely eaten as beans: they don't taste very nice and both animals and humans find them difficult to digest.  They're routinely processed into a host of “food-like substances” (Pollan).  Before they get anywhere near your plate, soya beans will have received some or all of the following treatments: multiple heat-treatments, pressure, cracking and crushing, chemical extractions, treatment with acids, alkalis and enzymes, bleaching, addition of  preservatives, supplements, colouring and flavouring, and finally molding into some shape to make it seem to be something it's not.  All this doesn't sound a very good way to produce wholesome food.

As you might expect, soya indeed presents several health issues.  However, add in GM soya and  these health concerns are raised to a whole new level.

Imported food from the United States

February 2011

Very few GM offerings have appeared in the shops, but ingredients can change so be on the alert.

Experience suggests that processed foods imported from America or made by American food companies are the ones to keep an eye on. In the past, the following have been spotted in various locations in the UK:

• Schwartz GM soya ‘Bacon Flavoured Salad Topping’ – designed to “add a little change a lot” (Schwartz is owned by US food company, McCormicks)
• Betty Crocker ‘BacOs’ bacon flavoured GM soya chips - “made with the goodness of soya” and “makes every bite better!”. (Betty Crocker is part of US food company General Mills; other products from this company include Cheerios (in partnership with Nestlé), Old El Paso, Yoplait, and Green Giant)
• Orville Redenbacher's GM ‘Popcorn Cakes’ - “a tasty guilt-free snack”, “perfect for active health-conscious people”. (Orville Redenbacher is part of US food company ConAgra Foods)
• Supercook spray-on food colouring with added GM oil. (Supercook is part of the Dr Oetker range; the company is European but the GM Supercook spray was made in the US)

Hershey's various CANDY BARS have their own story.

Soya

Soya – keep a wary eye on it

GM soya is perfectly legal in Europe and could appear in your food at any time. It must, however, be labelled. Check the small print of any soya-containing product you buy (except organic), even if it was non-GM the last time you looked.

The trick here is to know what is actually made of soya.

The soya origins of the final product may not be at all obvious:

• Schwartz “Bacon Flavour Bits” salad topping never came from a pig, they're soya (not to be confused with Danfood's “Bacon flavoured salad bits” which are wheat)
• you can get soya “milk”, soya “yoghurt”, soya “cream”, soya “ice-cream”, soya “cheese”, soya “mince” and soya “burgers” which never came from a cow
• “textured vegetable protein”, “TVP”, and “hydrolysed protein” are all soya

Soya as a human food is already problematic, but GM soya may be even worse. To find out more, check out WHY LOOK OUT FOR GM SOYA – February 2011
