(CNN) -- Federal and state agencies are tracking reported cases of Salmonella enteritidis, which has been linked to the current egg recall. Here's what officials have told CNN this week during a canvass of state health departments nationwide.
The state has seen a twofold increase in salmonella reports, with an uptick beginning in June, said Dr. Joli Weiss, foodborne disease epidemiologist for the state Department of Health Services. The state has seen 51 cases this year; normally it has reports of one to three a month, she said.
"There are no cases so far that we can confirm that are related to the recall," said Ed Barham of the Arkansas Department of Health.
There are cases the state is looking into, however. Barham said they're trying to get confirmation, but as of now there is no conclusive evidence.
The current cases of salmonella are geographically spread out, Barham said.
"We have several hundred cases confirmed in California," Michael Sicilia of the California Department of Public Health told CNN on Tuesday. "This is the most common type of salmonella, and we can't confirm if they are all related to eggs.
"There are probably more, but we haven't heard from those people yet," he said.
The outbreaks in California began in late May, when more than 30 people attending a prom and graduation party became sick. Tests confirmed the cause of illness was salmonella. The common link was a custard-filled pastry that was served at both the prom and the party.
Shell eggs were used in the filling of the pastries. Investigators identified these eggs as the source of the salmonella.
Outbreaks in California have occurred in San Diego County, Santa Clara County and Los Angeles County.
The Colorado Department of Public Health and Environment issued this in a statement:
"Colorado epidemiologists noted that over the past two months there has been an increase in reported cases of this strain of Salmonella enteritidis. Historically, an average of seven cases of this strain are reported in Colorado during the months of June and July. However, in 2010, a total of 28 cases were reported in June and July. Some of this increase likely is linked to this egg recall and includes cases from a recent outbreak involving The Fort restaurant in Jefferson County."
"Currently we have no cases linked with the recall," said Diana Lejardi of the Connecticut Department of Public Health.
The agency is working with both the Department of Agriculture and the Department of Consumer Protection to determine whether any tainted eggs have reached Connecticut. So far, there is no evidence that any eggs are linked to the recall.
"We are continuing to investigate," Lejardi said.
"We haven't experienced any illnesses related to the egg recall at this time," said Ravae Graham of the Georgia Department of Community Health. "But we are continuing to monitor our salmonella surveillance system."
Graham said Georgia usually experiences a seasonal increase in this particular salmonella pattern, and the department hasn't seen anything out of the ordinary compared with last year. About 2,000 cases of salmonella are reported annually in Georgia, with Salmonella enteritidis being the most common.
The state has seen no cases that can be connected to the egg recall, said Tom Shanahan from the Idaho Department of Health.
There have been seven reported cases of salmonella since June, but this is an average number, Shanahan said.
The department checked in with Albertson's because the chain distributes in their state, but the chain said the tainted eggs in question did not get sent to Idaho.
"We're watching for everything but just haven't seen anything," Shanahan said.
"We do not have any cases linked to the recall of the eggs at this time," said Melanie Arnold of the Illinois Department of Public Health.
However, Illinois did experience an outbreak in salmonella that was not associated with the egg recall earlier in the year, making their numbers higher than normal, Arnold said.
"So far this year we've had 86 cases of Salmonella enteritidis in Iowa," said Dr. Patricia Quinlisk from the Iowa Department of Health. However, none of those illnesses can be attributed to the egg recall at this time.
Last year, the state had a total of 86 cases, but Quinlisk said the department does not know what is behind the growth in numbers. The department investigates all cases of salmonella that are reported.
"We've seen no particular clusters, or outbreaks, or even individual cases that we can link back to any of the recalled eggs," Quinlisk said.
The state has seen no salmonella cases in connection with the tainted eggs, said Gwenda Bond from the Kentucky Department of Public Health. There has been no confirmation that contaminated eggs were shipped to the state.
The department is focused on getting the word out to restaurant associations and food retailers about egg safety in general, Bond said.
The state is not currently investigating any salmonella cases, said Ken Pastorick from the Louisiana Department of Health and Hospitals. Recently, Louisiana has seen nine unrelated cases that cannot be definitively linked to the egg recall.
The number of cases so far this year is average, Pastorick said.
The state has seen no uptick in cases compared to this time last year, said Karen Black from the Maryland Department of Health and Mental Hygiene.
"We are in good shape so far," Black said.
There have been no salmonella cases definitively linked to the egg recall, said Julia Hurley of the Massachusetts Department of Public Health.
Hurley said there's no way to tell if there have been more or fewer egg-related salmonella cases compared to last year, as the department does not generally do individual food interviews unless the case is part of an outbreak investigation.
According to the Centers for Disease Control and Prevention, there have been 766 cases of salmonella reported in Massachusetts in 2010, compared to 719 in 2009.
The state has seen no cases linked to the egg recall, and no increase in cases compared to this time last year, said James McCurtis from the Michigan Department of Community Health.
There have been 487 cases of salmonella reported in the state this year, according to the CDC. 2009 saw 615 cases.
The state's number of infected people in relation to the egg recall has jumped to 14, after seven more were identified over the weekend, according to the Minnesota Department of Health's website.
"The additional Salmonella enteritidis cases were identified as part of a restaurant outbreak in Bemidji, Minnesota, in May," according to the website.
The eggs were traced back to Hillandale Farms in Iowa.
Overall salmonella cases in Mississippi are actually down slightly, with no links to the egg recall, said Liz Sharlott from the Mississippi State Department of Health.
"We have not had any confirmed cases linked to the tainted eggs in Missouri at this point," said Kit Wagar of the Missouri Department of Health.
The department is investigating a few cases of salmonella, but this is not out of the ordinary, Wagar said. The state has between 700 and 800 cases of salmonella reported each year, so the department does investigations all of the time.
"We have no reason to think at this point that any of the cases we're looking at are linked to eggs," he said.
The state has eight confirmed salmonella cases, which isn't out of the ordinary, said Marla Augustine from the Nebraska Department of Health.
Nebraska generally sees between 200 and 250 cases of salmonella in a year. These current cases are dispersed throughout the state with no clustering, Augustine said.
The state has seen a spike in Salmonella enteritidis cases this year, said Martha Framstead from the Nevada State Health Department.
As of Tuesday, Nevada had 56 cases of this particular strain. However, cases are still under investigation, and none have been definitively linked to the egg recall, Framstead said.
Nevada had 20 cases of Salmonella enteritidis in 2008 and 14 cases in 2009, making 2010's total well above average.
"We haven't had any salmonella cases of late," said Jodie Dionne-Odom from the New Hampshire Department of Health and Human Services. "It's a common infection, so it certainly comes up, but we haven't had anything recently."
In New Hampshire, there were 261 cases of salmonella reported in 2009, and only 57 so far in 2010, Dionne-Odom said.
"We have no salmonella cases linked to the national outbreak, but we continue to do surveillance," said Marilyn Riley from the New Jersey Department of Health and Senior Services.
The state has seen no increase in salmonella reports in the last few months. New Jersey gets about 1,200 salmonella case reports each year, and there's been no noticeable difference in numbers so far this year, Riley said.
"We don't have any evidence of cases associated with the outbreak right now," said Deborah Busemeyer from the New Mexcio Department of health.
Busemeyer said that the affected eggs weren't distributed in New Mexico, and the number of salmonella cases this year is average for the state.
"We do not have any cases linked to the outbreak," said Peter Constantakes from the New York State Department of Health.
Constantakes said there are always cases around the state, but the number or cases are what would be expected in a normal year.
"None of the recalled eggs have been sold or shipped to New York markets," said New York Agriculture Commissioner Patrick Hooker. "However to err on the side of caution, our fleet of food safety inspectors remain on the lookout for recalled eggs at the retail level."
"We haven't seen any cases related to this recall," said Julie Henry of the North Carolina Department of Health and Human Services.
However, North Carolina was contacted by the FDA about the egg recall because of a salmonella outbreak back in April. The state is keeping a close eye, but there are no known salmonella cases currently.
The state has not seen any cases of Salmonella enteritidis that can be traced back to the egg recall, said Kirby Kruger from the North Dakota Department of Health.
Recently, two cases of the strain were reported, with 10 total so far this year. Kruger said these numbers are average.
"It's a small enough state where we get a fairly good idea of what's going on," Kruger said.
Although the state has some salmonella cases, "we haven't seen a spike in cases that we would expect if we were dealing with an outbreak," said Jen House from the Ohio Department of Health.
There weren't many of the affected eggs distributed in Ohio, and most eggs sold in the state are produced in the state, House said.
Earlier in the summer, there were a few salmonella outbreaks in geographic clusters, though none were related to the egg recall, House said. Still, Ohio still has an average number of reported salmonella cases.
In 2009, there were 915 cases of salmonella, according to the CDC website. So far this year, there have been 847.
"In terms of Salmonella enteritidis, we haven't seen an increase," House said.
The state has not seen any cases of illness related to the egg recall, said Pamela Williams of the Oklahoma State Department of Health.
As of Friday the state was investigating two cases, but found that neither was related to the recent salmonella outbreak in eggs.
The state has identified eight cases of Salmonella enteritidis at this time, with only one case being linked to the egg recall, said Emilio DeBess of the Oregon Department of Health.
DeBess said the affected person ate at a restaurant in California that was named in the outbreak. Otherwise, Oregon has not seen any other clusters of cases.
Salmonella enteritidis is a very common pattern seen in Oregon, and the department continue to keep watch for clusters of cases, he said.
As yet, the state does not know of a connection between any reported cases of Salmonella enteritidis and the egg recall, said Holli Senior from the Pennsylvania Department of Health. Cases are being reviewed and sent for further testing, Senior said.
There were 206 cases of salmonella in Pennsylvania in 2009 and only 108 so far this year, according to the CDC.
There have been no reported cases that the Department of Health believes are associated with the egg recall, said spokeswoman Ann Marie Beardsworth. The state is not investigating any cases.
The state is not investigating any cases associated with the current egg recall, said Thom Berry, spokesman for the South Carolina Department of Health and Environmental Control.
South Carolina is not seeing any higher than normal levels of salmonella, Berry said. There are no cases of Salmonella enteritidis that the state is investigating at this time, he said.
The state has had 13 reported cases of Salmonella enteritidis of the same type identified in this outbreak, since from February to June of this year. But none of these people said they had eaten raw or undercooked eggs, said state epidemiologist Lon Kightlinger.
It is not known whether these cases were related to the current outbreak, since this type of salmonella is common, he said. There have not been any cases reported since June.
So far in 2010 the state has had 69 cases of salmonella infection, which is below the 96 cases expected at this point in the year, he said.
The state has not identified any cases that are linked to the current egg recall, said Shelly Walker of the Tennessee Department of Health.
Although the state is investigating some cases, there is no indication that they're linked to the recall.
"We do see cases of that kind of salmonella," Walker said. "It's very, very common."
There has been no indication of a huge upswing in numbers, she said. Recently, there have been a number of cases in the Chattanooga area, but none are related to this particular outbreak.
While none has yet been directly linked to the egg recall, Texas has seen 165 illnesses as a result of salmonella since mid-May, said Christine Mann of the Texas Department of State Health Services.
The illnesses have been reported in 41 counties, so there's not one concentration that the department has seen, Mann said.
"It is a significant increase over the past five years," she said. "Some may be related to the egg recall, but at this time we have no definitive link."
The department is investigating some restaurant clusters, but that still wouldn't account for all of the cases, Mann said.
The investigations are ongoing, with no estimation for when they will be completed.
The state has seen a slightly above average amount of cases of salmonella this year, but none can be linked back to the egg recall, said Julia Hall of the Utah Department of Health.
"We still don't have confirmation that any of the eggs entered into Utah," Hall said. The FDA has record of one shipment of the affected eggs that was delivered to Utah, but there is no record that the company received the shipment. Whether the eggs actually entered into the state is still under investigation.
Many salmonella cases are located along the Wasatch front, but Hall attributes this simply to the high population in that area.
There are no reports of any recalled eggs or related cases of salmonella as of Thursday, a spokesman for the Vermont Department of Health said. The state is not investigating any salmonella cases at this time.
The state has had no confirmed cases of salmonella related to the egg outbreak, said spokeswoman Michelle Peregoy of the Virginia Department of Health.
The disease is common in the state; last year there were 1,058 cases of salmonella infection reported, she said. As of July there were 414 cases reported so far for 2010, which is on par with or under the expected number for half a year, she said.
While the Washington Department of Health is investigating salmonella cases, none are suspected to be related to the egg recall, said spokesman Donn Moyer.
It's been an average year so far with no noticeable uptick in cases, he said.
"We have 800 cases a year in Washington, so we're always investigating," Moyer said. "As of now, none are pointing in that direction."
The department will continue its investigations.
The state has 21 confirmed cases of salmonella in connection with the egg recall and is investigating one more probable case, said Beth Kaplan from the Wisconsin Department of Health.
The 21 confirmed cases were from the Kenosha area of Wisconsin, all in connection with a restaurant. Everyone infected at the restaurant had either ingested eggs or something else that could have been cross-contaminated, Kaplan said.
"At least compared with last year, we're ahead with this year's total," Kaplan said, noting that there were 135 cases of salmonella last year, compared with 168 cases this year already.
Kaplan said that some of the cases currently being investigated around the state probably don't have anything to do with the recall, but the investigations are still being conducted with an eye toward possible connections.
The state does not have any cases of salmonella associated with the current outbreak, said spokeswoman Kim Deti.
There were three reported cases of salmonella in the last two weeks, but these were found to be isolated incidents unrelated to any outbreak, she said. This is not unusual for this time of year, she said.
