Research conducted by Dr. Barakat Mahmoud at Mississippi State University lends further credence to irradiation as another line of defense against foodborne illness.

Specifically, Dr. Mahmoud’s research found that x-ray irradiation killed harmful bacteria in certain foods without affecting the quality or freshness of the food, and the elimination of the bacteria even extended the food’s shelf life.

Through x-ray irradiation, Dr. Mahmoud eliminated the Vibrio bacteria from oysters without altering the quality of the food in any other way. In addition to seafood, Dr. Mahmoud’s research also focused on produce. Here too, x-rays destroyed the harmful bacteria in leafy greens but left the greens fresh and nutritious. Notably, leafy greens were deemed the riskiest food regulated by the FDA in 2009.

The notion of food irradiation has been around for quite some time, but it is not without limitations. X-ray irradiation, however, in comparison to gamma ray and electron beam radiation, may offer more promise. First, consumers are wary of irradiated foods even though irradiation has proven extremely safe. Dr. Mahmoud hopes consumers will feel more secure with x-ray technology since it is more familiar to them.

Second, the introduction of most types of irradiation into the food manufacturing process is not easily accomplished. Dr. Mahmoud does believe that x-ray irradiation “can be effectively used in large-scale commercial operations,” however, and is presenting his research across the country. Indeed, one advantage of x-ray irradiation is that it can be accomplished at the manufacturing facility, whereas some other technologies require trucking products to another location.

In any event, we send our thanks to the scientists, educators, government agencies and food manufacturers who continue their efforts to research new technologies -- like x-ray irradiation -- to help make the food we eat as safe as it can be.

With Halloween fast approaching, it would seem the perfect time to worry the masses.

Researchers from the Center for Science in the Public Interest (“CSPI”), for instance, have just compiled nearly twenty years of CDC data, and used it to create a list of the riskiest foods to consume. In turn, some major news outlets, including CNN, quickly publicized the findings. Click on the following link to view the CSPI Study.

The study attempted to determine the relative risk of select foods by examining the frequency of past food-borne illness outbreaks associated with each. The findings, ironically, are nearly identical to the Food Guide Pyramid, which tells us what, and how much, food we should eat in order to stay healthy.

In any event, according to the CSPI study, the ten most risky foods are as follows:

1. Leafy Greens: 363 outbreaks (13,568 reported cases of illness);
2. Eggs: 352 outbreaks (11,163 reported cases of illness);
3. Tuna: 268 outbreaks (2341 reported cases of illness);
4. Oysters: 132 outbreaks (3409 reported cases of illness);
5. Potatoes: 108 outbreaks (3659 reported cases of illness);
6. Cheese: 83 outbreaks (2761 reported cases of illness);
7. Ice Cream: 74 outbreaks (2594 reported cases of illness);
8. Tomatoes: 31 outbreaks (3292 reported cases of illness);
9. Sprouts: 31 outbreaks (2022 reported cases of illness); and
10. Berries: 25 outbreaks (3397 reported cases of illness).

The implied lesson from the findings seems to be that we should, in order to minimize our risk of getting sick, avoid eating fruits, vegetables, dairy products and seafood. In turn, it would seem, a diet which consists strictly of beef, chicken and candy would be exactly what the doctor ordered.

In my view, scaring people away from certian foods doesn’t help promote food safety. And, warning people not to eat fruits and vegetables may be a bit short-sighted. Leafy greens, for instance, are served in virtually every single salad and on every single sandwich; that translates to nearly a billion safe servings every single day. The same is true for other foods on the list, including countless fruits and most vegetables.

So, in twenty years, we have less than 14,000 reported cases of people getting sick from leafy greens? You do the math. This is really no different than arguing that visiting the grocery store (to buy your produce) is an inherently dangerous activity because, every so often, someone trips.

Moreover, in my house, it is not what you eat that determines the risk, but rather who made it. My father, for instance, didn’t stop at just cooking our food. He cremated it. In this regard, most foods we enjoy are perfectly safe when properly handled and cooked to a thousand degrees centigrade (or, 160 degrees fahrenheit as recommended by FSIS).

In any event, recognizing that nothing in our world is without risk, I’ll continue to take my chances with a healthy diet and tasty food. And, despite its safety record, the candy can wait until Halloween. For now, I’m going to go eat a salad.

Agriculture Secretary Tom Vilsack and Health and Human Services Secretary Kathleen Sebelius have announced that “prevention and partnership” will guide their departments' efforts to safeguard our food supply. These announcements are based on the public health principles embraced by the White House Food Safety Working Group led by Sebelius and Vilsack.

According to Vilsack, "making prevention a priority is critical to reducing food-borne illness and one of the three food safety principles of President Obama's Food Safety Working Group.” In turn, Vilsack and Sebelius announced the following new initiatives designed to accomplish these goals.

Beef Safety - E. Coli Testing Of Bench Trimmings

For starters, the USDA's Food Safety Inspection Service (FSIS) is issuing guidance for inspectors to begin conducting routine sampling of bench trim for E. coli. In the past, the FSIS had not routinely tested bench trim. Rather, FSIS started E. coli O157:H7 testing with ground beef, and expanded testing to other beef components used in ground beef. Bench trim, which will now be tested as well, includes pieces left over from steaks and other cuts that are then used to make ground beef. FSIS is also issuing streamlined, consolidated instructions to its personnel for inspection, sampling and other actions to help reduce E. coli O157:H7 in beef.

Produce Safety – New Draft Guidance

Secretary Sebelius also praised new draft guidances prepared by the FDA, an agency within HHS, aimed at minimizing contamination in leafy greens, tomatoes, and melons. According to Sebelius, "the proposed controls provide a guide for growers and processors to follow so they may better protect their produce from becoming contaminated." The draft guidances also represent a shift in strategy for the FDA, from a food safety system that often has been reactive to one that is based on preventing food-borne hazards. Click on the following link for information on the Draft FDA Guidances.

Although the new controls are aimed at preventing contamination in the first instance, Secretary Sebelius also confirmed that consumers play a vital role in ensuring the safety of the fresh produce they eat. In turn, she offered the following tips from the CDC:

• Buy wisely. Don't buy produce that is bruised or damaged. When buying fresh cut produce, choose only items that are refrigerated or surrounded by ice.

• Refrigerate promptly. Certain perishable fresh fruits and vegetables (e.g., strawberries, lettuce, herbs, and mushrooms) should be stored in a clean refrigerator at a temperature of 40ºF or below. If you aren't sure whether an item should be refrigerated, ask your grocer. Produce that is purchased pre-cut or peeled should be refrigerated within two hours.

• Prepare produce with clean hands. Wash hands for 20 seconds with warm water and soap before and after preparing fresh produce.

• Wash produce thoroughly. Rinse fruits and vegetables under running water. Scrub firm produce such as melons and cucumbers with a clean produce brush. All unpackaged fruits and vegetables, as well as those packaged and not marked pre-washed, should be thoroughly rinsed before eating. This includes produce grown conventionally or organically at home, or produce from a grocery store or farmer's market.

• Do not cross contaminate. Don't give bacteria the opportunity to spread from one food to another. Consider using one cutting board only for foods that will be cooked such as raw meat, and another one for ready-to-eat foods such as raw fruits and vegetables.

According to FDA Commissioner Margaret A. Hamburg, the new draft guidances embody the Administration’s and FDA’s prevention-oriented food safety strategy.” She also confirmed that, while the proposals are still in draft form, “they will be made final as soon as possible after public comment, and will be followed within two years by enforceable standards for fresh produce.”
