It’s sometimes fun to jibe at health types – local, state, federal – but they have a tough job and I’d be lousy at it.

JoNel Aleccia of NBC News reports Chinese government officials overseeing plants that make chicken jerky pet treats blamed for thousands of illnesses and deaths among American dogs have refused to allow U.S. inspectors to collect samples for independent analysis, newly released records show.

Investigators with the federal Food and Drug Administration came away empty-handed after conducting April inspections at four jerky treat manufacturing sites in Liaocheng and Jinan, China, according to the records.

The plants make pet treats sold by the St. Louis-based Nestle Purina PetCare Co., including the popular Waggin’ Train jerky brands.

Chinese officials stipulated that FDA officials could collect samples only if they agreed to specific conditions, including a requirement that the samples be tested in Chinese-run laboratories.

As a result, “no samples were collected during this inspection,” wrote Dennis L. Doupnik, an FDA investigator who visited the sites.

In addition, the reports showed that the Chinese plants conducted either no laboratory tests or only sporadic tests of the raw materials, including meat used in treats fed to many of the 78.2 million pet dogs in the U.S.

But where’s the company at the center of some 2,000 pet illnesses, Nestle Purina? Hiding behind government, although the company makes the profit.

Elizabeth Mawaka, 57, a Hartford, Conn., woman who says her two Boston terriers, Max and Toby, died after eating tainted treats, got it right when she called on Nestle Purina to demand that samples be released to the FDA.

“It really comes down to the company,” said Mawaka, who is suing jerky treat makers and retailers. “We can talk all we want about China, but it’s really the company.”

However, a Nestle Purina spokesthingy said the inspections demonstrated no problems with the firm’s products, no evidence that they’ve led to illnesses in animals in the U.S., and that the terms of the inspection were set by the U.S. and Chinese governments, not by Nestle Purina or the manufacturing site officials.
