Food safety issue or regulatory compliance issue, asks Richard Bennett
Growers are always quick to make the distinction. There’s a big difference between foodborne illness due to microbiological contamination and exceeding the Maximum Residue Limit (MRL) for an agricultural chemical. The smallest traces of a human pathogen can lead to much suffering, even death, but the many-fold human safety buffer built in to the regulatory pesticide limits means that many, many kilograms, if not tonnes, of offending fruit or vegetable would need to be consumed before ill effects from the pesticide are suffered.

Hazelnut growers target pathogens, pests
Mateusz Perkowski writes: Heavily shaded hazelnut orchards may discourage salmonella from lingering on the ground, but the conclusions for growers remain uncertain, according to an orchard researcher.
Ground temperatures in heavily shaded hazelnut orchards appear to fall below the temperature range in which salmonella thrives, compared to orchards with less shade cover, said Bruce Lampinen, a tree nut specialist with the University of California Cooperative Extension.
The results in Oregon hazelnut orchards were greatly different than in California almond and walnut orchards, where heavy shade cover seems to improve conditions for salmonella, he said.
