Q and A: Hydroponics

Q.  I would love to hear what you think about hydroponic food. My instincts tell me that organic soil is full of life and traces of nutrients and elements we don’t fully understand and here we have another frankenfood that is scientifically derived.

A.  Frankenfood is too strong but I’m basically with you on this one.  I don’t get hydroponics.  Obviously scientists have figured out enough about plant nutrient requirements to keep them alive in water and nutrient broth but what’s the point?  Soil works really well and is bound to contain substances we don’t even know about.  These may even influence taste.

Chefs say even the best of hydroponic vegetables, according to a recent New York Times article, are not considered serious replacements for field-grown lettuces because they can’t reproduce the flavor.

My suspicion?  People who like hydroponics don’t like getting their hands dirty (but isn’t that half the fun?).

Food safety: this time, tomatoes

So now tomatoes are contaminated with Salmonella, this time with the uncommon serotype, Saintpaul, and the FDA says not to eat tomatoes from a bunch of states in the Southwest.  But the New Mexico government says the contaminated tomatoes come from Mexico.  If this is correct, it’s globalization time again.  The FDA notes that tomatoes from everywhere are now coming into harvest. That is why, in 2007, the agency started a “tomato safety initiative” to get growers to take action to prevent Salmonella contamination. Initiatives are voluntary, here and in Mexico. Surely, it is time for mandatory? And mandatory import inspections?  Michael Doyle, a food safety expert based at the University of Georgia, says globalization raises food safety risks. This may seem evident, but I like his quote: “It is the industry that is responsible for producing safe foods. It is the government’s responsibility to verify that they are producing safe foods.”

As for the perspective of strong supporters of the produce industry, check out what the Perishable Pundit has to say about the way the FDA is handling this incident.   What he calls the “gracious” comments of California tomato growers are also worth a look.
