I learned recently that ALL California wines contain the herbicide glyphosate (Roundup) which is a probable carcinogen. Some wines have higher levels of glyphosate than others. Do you know the glyphosate levels in your red wines?

Oh good gawd.

The more important question is not presence, but concentration and duration of exposure. Tap water, beer, soda, wine, etc. may contain not only glyphosate but other toxic chemicals which are regrettably ubiquitous in our environment, but at parts per trillion/quadrillion/quintillion levels or lower. While such chemicals may be toxic, there may be minimal hazard. Hazard is a function of: toxicity, concentration, and duration of exposure. A good example is salt certainly not a hazard with appropriate dietary use. Lack of salt is in fact a hazard. Humans require about 2,300 mg (2.3 g) salt/day with a maximum of 6 g, about a teaspoon, per day. The above is certainly not excusing the presence of toxics in anything. Unwise human practices have got us where we are and, regrettably, understanding the limits of perfection is essential to our mental health. L. Naylor
