Meyer went to the hospital a week later with what turned out to be a rare and deadly strain of E. coli bacteria that caused thousands of illnesses, mostly in Germany. He would spend the next month in a Massachusetts hospital, much of the time a delirium, while doctors worked around the clock to save his life.
Meyer is one of six U.S. cases linked to the German outbreak and he's the first to talk about his terrible experience.
"It was 30 days of hell," said his wife, Loreen.
Meyer was in Hamburg as that city was emerging as the epicenter of a food poisoning disaster that would be among the deadliest in memory. More than 4,000 people in Germany and other countries became ill since the outbreak was detected in May, including several hundred who developed a serious complication that can lead to kidney failure. At least 53 died.
The outbreak ultimately was traced to a batch of fenugreek seeds from Egypt. The seeds are sometimes used as a spice in cooking, the sprouts are used in salads.
Meyer believes he must have eaten fenugreek while attending a business meeting at the Hamburg hotel. He thinks the tainted seeds, or sprouts, could have been in the fresh fruits and vegetables at a breakfast bar. If so, there would be some irony: It's hard to find good produce during business trips, and Meyer had welcomed the opportunity to eat healthy.
"In this case, it backfired," he said.
Massachusetts state health officials confirmed he was infected with the rare German E. coli strain.
Slow, deadly onset
Some common forms of food poisoning can cause symptoms within a day of eating tainted food, but Meyer said he felt no ill effects during a six-day European business trip that included two days in Hamburg and a brief stop in France afterward. He returned home on May 13 feeling fine.
However, this E. coli bug takes a week to announce its presence. Meyer first became aware something was wrong on May 18. He was at his desk at Senior Aerospace that morning when his abdomen began hurting.
At 52, he is a cyclist who says he's never had food poisoning, but on that day he went home in pain.
By midafternoon, he was hit with bloody diarrhea and a dawning sense of alarm.
"Whatever it was, it wasn't a minor thing," Meyer said.
His wife Loreen, a high school biology teacher, was home by then and worried. She took him to nearby Milford Regional Medical Center.
Doctors there weren't able to diagnose him. They recommended follow-up with a gastroenterologist the next day and sent him home for the night. But when he got home the diarrhea accelerated.
"Every hour, and then it started getting even closer," he recalled.
Loreen took him back to the hospital that night and he was admitted.
Though it all happened less than two months ago, Meyer's memory is fuzzy on what happened the next several weeks. He had intense stomach pain and his kidneys stopped working. Doctors put him on fluids to rehydrate him. They treated him with antibiotics, and cleansed his blood using dialysis and other measures.
The infection affected his mind. He recalled staring at a clock in his hospital room and not being able to tell time.
"I was thinking, 'Why do they have this strange clock in here, and why is it set up differently?' "
Meyer said he grew paranoid, believing that his doctors had written him off for dead. Doctors had not given up on him, but were perplexed. A test for the most dangerous form of E. coli familiar to Americans came back negative. They sent specimens for additional analysis to lab with the Centers for Disease Control and Prevention lab in Atlanta.
In early June, CDC confirmed it was the German strain.
Around that time, he had begun to recover. His kidneys were improving. His awareness returned. He was moved out of intensive care, and on June 17 he was sent home.
But he was far from normal. He and his wife said his muscles had atrophied, his red blood cell count was still down, and the lining of his colon had become a layer of dead tissue, unable to absorb nutrients. A man who had been an athletic 6-foot-2 and 185 pounds was down to 162 pounds and able to walk only short distances using a cane. He was hungry, though, eating two breakfasts, two lunches and two dinners each day.
"He had such a huge appetite because he was still not able to absorb as many nutrients," his wife said.
Now he's up to 170 pounds and working part days from home. He's been in physical therapy and regaining his strength, though he's months away from the kind of vigorous exercise he used to do.
Meyer and his wife contacted a local attorney, saying they were worried about possible problems with getting health insurance to pay his hospital bills. That turned out not to be an issue. But the attorney referred the couple to Bill Marler, a Seattle lawyer considered the nation's pre-eminent plaintiff's attorney in food poisoning cases.
Marler is looking into the possibility of a lawsuit, with potential targets including the company that owns the Hamburg hotel where Meyer stayed.
For his part, Meyer feels lucky to have survived, crediting his doctors for saving his life and his good health and fitness before the illness for helping him get through it.
"Many unfortunate people didn't survive," he said. "It really is a frightening thing."
