Did someone say ‘recall’?

Beef safety questioned after 20 such incidents in ‘07

December 26, 2007


— For beef lovers, 2007 will go down as another year of eating dangerously.

Since the spring, meat suppliers have recalled more than 30 million pounds of ground beef contaminated with the potentially lethal bacteria E. coli O157:H7, including the 21.7 million pounds recalled by New Jersey-based Topps Meat in September.

After three relatively quiet years, the 20 recalls this year have raised new doubts about whether the beef industry's attempts to keep the pathogen out of ground beef, and the government's oversight of those efforts, are working.

Agriculture Department officials, who oversee the safety of pork, beef and poultry, say they did not recognize that anything was seriously amiss with the beef supply until the Topps recall hit.

Microbiologists say the prevalence of E. coli O157:H7 in the environment is highly variable, and no one can say with certainty what caused the spike in outbreaks. In several instances this year, however, USDA officials missed red flags and were slow to correct longstanding deficiencies in the way they monitor beef processors' efforts to contain the pathogen.

USDA officials did not learn that Topps had begun testing its ground beef less frequently until the recall. Recurring sanitation problems at a United Food Group plant in Vernon, Calif., that later recalled 75,000 pounds of ground beef did not trigger further enforcement actions because the agency had not told inspectors what to do about repeat violations. The recall was eventually expanded to 5.7 million pounds.

Critics said the agency missed an opportunity to strengthen its early-warning system by not keeping track of every instance when a plant found the dangerous strain of E. coli in raw ground beef.

Inspections postponed

The department has postponed plans to target inspections at plants that had a record of problems because officials do not know which plants pose the greatest risks.

Similar lapses have surfaced during the seven years since meat processors were required to come up with scientifically based plans to contain and control pathogens. In 2002, USDA officials did not know that the E. coli strain had been detected in ground beef at ConAgra's Greeley, Colo., plant 63 times in the weeks leading up to a massive recall. The agency had been testing for the bacteria in raw ground beef since 1994, but skipped ConAgra's plants under a policy that exempted the largest processors. USDA now tests ground beef at every plant at least once a month, while self-testing at plants remains voluntary.

E. coli O157:H7 is a variant of the bacteria normally found in animal and human intestines, and it spreads easily among cattle. Surveys of feedlots have shown that in the summer, 63 to 100 percent of cattle could be infected, according to the Centers for Disease Control and Prevention. The bacteria are shed in feces and can contaminate meat during the slaughtering process.

Bacteria increasing

For years, USDA testing showed the bacteria's prevalence in raw ground beef was increasing. Then it dropped by more than 80 percent between 2000 and 2005. The number of people who got sick also began to fall. In 2006, the CDC reported a 29 percent decrease in illnesses caused by E. coli O157:H7, compared with a baseline established from 1996 to 1998.

The beef industry and federal regulators thought such industry interventions as steam vacuums, pasteurization and acid washes were keeping the bacteria off meat. They were reluctant to question their presumed success, even as cases of human illness began rising over the past two years. When asked by lawmakers about the uptick in illness at a hearing in April, USDA officials said contaminated produce was the likely culprit. The day after the hearing, the USDA announced two beef recalls that were prompted by people becoming sick.

By the time Americans fired up their grills for the Fourth of July, cases of human illness had prompted five beef recalls.

"We began to believe we may have a problem, but we weren't sure," Richard Raymond, undersecretary of agriculture for food safety, said in an interview last week. At that point, however, the agency "wasn't ready to make sweeping changes."

Then the Topps recall occurred. Raymond called it a "wake-up call."

Effectively managing E. coli?

The recalls have Carol Tucker Foreman, a former assistant secretary of agriculture who is now with the Consumer Federation of America, questioning whether regulators and the industry ever had a handle on O157:H7.

"I had assumed the steps the companies are taking were effective," she said. "Now I don't know if the falloff during the past several years was the result of the steps the industry took or whether we had a period of time where there wasn't much E. coli."

Stan Painter, a USDA inspector and representative of the inspectors' union, said not much has changed since the ConAgra recall.

"We're relying totally on the plant. We're doing very little testing ourselves," Painter said. "We're saying, 'You tell us you have a problem. And if we don't hear from you, we assume you don't have a problem.' "

Last week, in a report requested by Rep. Rosa DeLauro, D-Conn., the USDA inspector general said the agency lacked the data, management controls and technology to identify the plants at greatest risk for contamination. The USDA has not assessed the food safety plans at all processing plants. At 15 facilities, the inspector general found no record that inspectors have been reviewing plant test results at least once a week.
