Thanks, Jim, and welcome to everyone listening on the conference call, as well as those joining us via the Internet. Jim has already reported on the overall sales and profit performance for the first quarter of our fiscal year. In the next few minutes, I'm going to give you some color behind those results and I'll start by discussing the performance of the Food Safety group.
Revenues for the Food Safety segment were up 3% in the first quarter. But these results stack up against difficult comparisons from last year's first quarter when, as Jim said, we hit the tail of the aflatoxin outbreak from the 2012 calendar year and we're in the middle stages of the horse meat speciation scandal in the U.K. Without those headwinds, revenue growth would have been more in the 7% range.
Markets, which were strong for our Lansing-based diagnostic group for grocery products which were up 16%; dairy which was up 33%; and the commercial lab group up 9%. Our Neogen Europe operations led the way for the quarter with sales up 9%. This growth was on top of growth of 54% in last year's first quarter, which resulted from the speciation outbreak in the U.K. The biggest growth driver for the quarter this year was the 52% increase in genomic testing services in Europe, the result of our investment in direct sales personnel based in Europe to capture business, coupled with the strong product offering in this important market.
Neogen Latino America, our business based in Mexico City, had a 77% revenue increase as they took over a number of customers in Mexico and Central America formerly served by our Lexington operations, based on their increased capabilities to serve those customers directly.
Neogen do Brazil had a 12% increase in its Food Safety product sales, with a large one-time genomic research project in the prior year resulted in a 9% overall revenue decline in the current quarter. We've made significant investments in personnel and infrastructure in both Brazil and Mexico in the past year and have high growth expectations for these businesses and markets going forward.
A number of our product lines contributed to Food Safety's first quarter results. Revenues for our industry-leading product line to detect inadvertent allergen contamination, which includes diagnostic tests to determine the presence of milk, peanuts and processed soy, amongst others, continues to be robust and were up 12% in the quarter. Milk test kit sales were particularly strong, up 28%. We continue to strengthen our allergen test kit product portfolio and recently adding new test for contaminants such as mustards and believe we'll continue to capture share in this growing market segment.
Our AccuPoint line, which is used to detect general sanitation and cleanliness in food processing environments, had a 6% increase in revenues during the quarter for the disposable samplers. We've invested over $1 million in new automation equipment to produce our next generation sampler, which will be introduced in the very near future.
Revenues from products such as ampouled media and filters used to test and monitor water quality at beverage manufacturers rose 18% in the quarter, continuing their strong recent growth as we penetrate this growing and important market.
Although our natural toxin product sales decreased 4% compared to last year due to that tail of that aflatoxin outbreak from calendar 2012, DON sales increased 11% in the quarter based on sporadic outbreaks of DON across the U.S. in the current crops. This should be the last difficult comparative quarter related to that aflatoxin outbreak.
Revenues for our test to detect the presence of antibiotics in milk declined by 12% in the quarter due primarily to order timing at a large European distributor and changing testing regulations in the Eastern European markets for these products.
We had 16% growth in sales of the consumable vials used in the Soleris line of optical microbial test systems, which are used to detect spoilage or organisms like yeast and molds. Our placement of equipment in this product line declined 44% in the quarter after a strong finish to the 2014 fiscal year.
I believe, as we've discussed in previous calls, this product line can give lumpy results due to the timing of equipment placements. The prospect pipeline for equipment remains very strong and we believe that we'll see increased equipment revenues as the year progresses and like the razor-razorblade model, this will give rise to even more consumables, which carry good margins.
The Animal Safety segment achieved revenue growth of 28% in the first quarter, aided by the recent acquisitions of SyrVet, Prima Tech and Chem-Tech. Animal Safety's Lexington division recorded revenue increases of almost 16% in the quarter. In addition to the increase provided from the acquisitions, our line of patented D3 detectable needles were up 27%. Our diagnostic line grew 22%, aided in part by forensic kit sales to commercial labs. Now these increases offset a 16% decline in our Disposable business, which we believe is due to order timing and which is a lower margin product line for us.
Within our Animal Care Line, sales of the wound care product declined by almost $1 million due to a competitor, which had been shut down coming back into the market. And the distributed antibiotic product declined $210,000 due to our withdrawal of their product from the market.
Animal Safety Division, which is located in Randolph, Wisconsin, and produces rodenticides and cleaners and disinfectants, which are important pieces of effective biosecurity programs maintained by animal protein producers, recorded flat sales for the quarter. A $1.2 million increase in rodenticide sales resulting from a bull [ph] outbreak in the Northwest U.S. was offset by a similar decline in cleaners and disinfectants due to the transfer of some business to Neogen LA and lower international shipments.
Chem-Tech, the insecticide business based in Pleasantville, Iowa, which we acquired in January, provided $5.1 million in sales this quarter, which was higher than budgeted and we're excited about its future.
GeneSeek, our genomics-based testing and bioinformatics business located in Lincoln, Nebraska had a strong quarter, with a revenue increase of 12% with particular gains in the swine market, a significant poultry genotyping project and continued strength in the dairy and beef cattle markets.
Gross margins were 50.4% for the quarter compared to 51.9% in last year's first quarter. The change there reflects a shift in product mix towards Animal Safety products. We were pleased that gross margins rebounded from last year's final 3 quarters to get back to the 50% level. And improvements over those quarters reflects improved product mix within the Animal Safety segment and better efficiencies realized at GeneSeek, in part due to its move to its new operations in Lincoln.
Overall, operating expenses were up 15% compared to last year's first quarter. Sales and marketing expenses increased 18%, primarily reflecting the impact of hires made in fiscal 2014 and increases in shipping due to the increased revenue for the quarter.
G&A expenses rose 9% for the quarter, due primarily to higher amortization expenses resulting from our recent acquisitions and increased stock option expense. Each of those expenses are noncash charges.
R&D expenses increased 15% over the prior year due to outside services and cost incurred in scaling of several products for larger manufacturing batch sizes. With the 15.5% increase in revenue and solid gross margins of 50.4%, we were able to generate operating income of $13.4 million, an increase of 8.2% or $1 million over last year. Expressed as a percentage of revenues, as Jim indicated, operating income was 19.9% compared to 21.2% last year. The quarter was favorably impacted by a $240,000 pickup we recorded in other income below the operating income line. This related to the earnout paid to the former owner of SyrVet.
Last year in the first quarter, we recognized approximately $630,000 in foreign currency translation losses in other income and expense, as a number of currencies in countries we operate in devalued against the U.S. dollar.
On the balance sheet. Our receivable balance declined slightly compared to year end and our collection period improved by 2 days. Inventory increased by $3.9 million or 8%. Approximately $1 million of that increase was due to lack of trucks to ship product over the Labor Day weekend, which was the close of our quarter.
We're working hard as a company to improve our inventory turnover and have programs in place at each operation to make that happen. We finished the quarter with $88 million in cash and marketable securities compared to $76 million we had at the end of May, reflecting the strong cash generation from the company's operations.
While we're pleased with the overall operating -- improved operating results for our first quarter, we realized that we need to accelerate the organic growth performance of our businesses. Each group has some good tailwinds behind it and we're excited about the remainder of the year ahead.
Thanks for your attention. At this point, I'll turn it back to Jim for his comments.
